VM_FAULT_MINOR was finally removed in the 4.7 Linux Kernel. According
to the below documentation, we should be returning a bitmask. In this
case, we are not handling the fault and should return 0, which
happens to be what VM_FAULT_MINOR was defined as anyway.
"The vma's ->fault is responsible for returning a bitmask of
VM_FAULT_xxx flags that give details about how the
fault was handled.
Replace the reference to VM_FAULT_MINOR with 0.

Fix memory leak:

outstanding descriptors at the time of driver shutdown
are not getting freed.
2) in ol_tx_ll_fast where in case packet fails to download,

it is not getting freed.

Proapagation from qcacld-2.0 to qcacld-3.0.
Currently pktstats are stored in static allocated memory. This
pkt stats can be accessed using
1) procEntry function
2) hal_proxy_daemon
If user access it using procEntry then read pointer is moved ahead
in static memory array because of which incomplete data goes when
queried using hal_proxy_daemon.
Fix this by maintaining the pktstats in link list. When the
request comes from hal_proxy_daemon, complete data is sent
to it from this link list

In USB solution, hif_usb_remove costs ~25s after card unplugged.
Test step is simple, do p2p listen, then unplug card. Sme session
close costs 15s. When do p2p listen, scan will be issued to fw, but this
cmd is stuck in smeScanCmdActiveList which cause session close cmd
eSmeCommandDelStaSession blocked and the timeout is 15s.
This solution is that remove scan from smeScanCmdActiveList
if scan cmd pending in active list when close session.

qcacld-2.0 to qcacld-3.0 propagation
In a SNS case, driver receives ASSOC Req during the SAP
Stopping. The SAP stopping will issue WMI_VDEV_DOWN_CMDID
WMI command to firmware. And ASSOC req frame processing
will issue a WMI_PEER_CREATE_CMDID WMI command to firmware.
Then the firmware crash happens because firmware can't find
the necessary BSS information to create the peer. Firmware
doesn't support peer create after BSS down.
The fix is to ignore the ASSOC Req frame while the deleting
BSS is ongoing.

qcacld-2.0 to qcacld-3.0 propagation
In case of P2P device and P2P GO using seperated
interface, if P2P Device interface listen (remain on
channel) with long duration is active, P2P GO interface
vdev start command will be timeout.
In shared interface case, driver will cancel existing
P2P listen during interface type changing from P2P device
to P2P GO in __wlan_hdd_cfg80211_change_iface. There
is no such issue.
This fix is to extend the canceling logic just before P2P GO
starting to avoid the vdev start timeout in first case.

qcacld-2.0 to qcacld-3.0 propagation
It's a fix for sns issue. Set DUT as sap, ref client sends assoc req
to DUT and as part of this frame processing lim does ADD_STA and posts
eWNI_SME_ASSOC_IND to sme layer. Before SME layer sends eWNI_SME_ASSOC_CNF,
DUT receives auth frame which triggers deauth. In this case lim layer
will delete ref client's related info, but wma layer doesn't get any
notification.
To fix this lim has to notify wma to do DEL_STA for that peer.

Currently tx_frm_download_comp_event is used in Mcthread and destroyed
in wma_stop, when wma_stop is called, Mcthread has not exited yet.
In stress test, this event is destoryed but Mcthread is still using,
so crash occurs.
Solution is that destroy event in wma_close to avoid the case that after
destroy this event is still used.
