cld80211_oem_rsp_alloc_skb api is used to alloc skb for reply msg.
A static buffer pointer is returned from this reentrant func
which can be called by kworker and scheduler thread at same
time resulting single buffer access by both threads. After
kworker thread freeing this skb, scheduler is further updating
data in this skb resulting in page fault error. Use local
skb pointer to avoid such race conditions

This is a propagation of qcacld-2.0 commit 98821c7dcf49d ("qcacld-2.0:
Add CONFIG_MULTI_IF_LOG to support multi if log"). Add CONFIG_MULTI_IF_LOG
to support multi if log by assigning the specific netlink protocol
when dual wlan cards are loaded.

Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within utils replace any such comparisons with logical
operations performed on the pointer itself.

On high throughput mode, send a message to perfd, through
cnss-daemon, to set the min freq for perf cluster to 700 KHz,
and release it on transition to low throughput.
Goes with corresponding changes on cnss-daemon (1834087).

Current cld80211 nl message size depends on PAGE_SIZE. PAGE_SIZE
can be 4K and thus it's limiting the maximum nl message size to
4K bytes. Make the max supported nl message size to 8K bytes
irrespective of PAGE_SIZE.

Currently nl_srv_bcast() and nl_srv_ucast() allocate a temporary
buffer to hold the netlink message which is subsequently sent to
userspace. The value returned by qdf_mem_malloc() is not checked for
NULL, and hence if NULL is returned it will be dereferenced.
However in reality a temporary buffer is not required. Update the
functions to directly send the message from the skb.

Presently if the module name is changed to something other than wlan,
then MULTI_IF_NAME is defined and cnss diag log can't be captured
because the driver doesn't register itself to cnss_logger module.
Add fix to resolve this issue.
Also add free skb buffer operation for one case to sync with qcacld-2.0.

wlan_nlink_common.h include linux/if.h, and linux/if.h
refers to 'struct sockaddr' which is defined in
linux/socket.h, and so it include linux/socket.h;
however, in userspace, linux/socket.h doesn't define
'sockaddr', so it will cause errors when compiling
userspace APP if it includs wlan_nlink_common.h.
Add macro __KERNEL__ to determine which header file
should be included:
For userspace, include net/if.h, it will include
sys/socket.h, which is for userspace;
for kernel space, include linux/if.h.
