Send correct channel list to Firmware. When cfg80211 is enabled, STA
is scanning in a set of wrong channels. When scan callback happens
from cfg80211 module the cfg80211 module gives us the channel numbers.
There are some channel numbers which are same in both 5GHz and in
2.4Ghz bands. For example, channel number 1 maps to frequency 4942MHz
in 5GHz band, but in 2.4GHz band channel number 1 maps to frequency
2412MHz. So cfg80211 may give us a wrong channel number. Since we have
the exact frequency of the channel we should use that instead of the
one given by cfg80211.
The channel object given to the driver by cfg80211 during scan callback
is the same as the one registered to cfg80211 by the driver. So we can
use the channel frequency inside the channel object for scan which is
not changed by the cfg80211 module.
Use regdb function to convert channel number to frequency while receiving
scan entries from FW. Use pdev band (5/2.4GHz) information to map to
correct 2.4Ghz/5Ghz channel frequency.
Half/Quarter rate flags in the scan_ctrl_flags are not set. Set
Half/Quarter rate flags in scan_ctrl_flags.

In existing code scan queue cleanup is done during radio detach,
leading to access of freed vdev netdev.
Extend cfg80211 scan cleanup API to support netdev level cleanup.

When invoked wlan_cfg80211_cleanup_scan_queue, it will try to clean
up pending scan requests in queue from kernel. However, when the
netdevice is down, this request could be already freed by kernel.
To fix this issue, also add the pointer to netdevice in scan_req
so what we can check the status of netdevice in scan_req instead
of cfg80211_scan_request which might already be freed for this case.

Commit fb9d5acfed and 645749571d introduce an API to deinit scan
runtime suspend lock in order to fix a memory leak issue. However,
it breaks SSR because scan lock init and deinit are not matching
during SSR which results double free happens in the rmmod after
SSR. Add the API to init scan runtime suspend lock so that it can
be added in the correct place during SSR.

On framework initiated scan, ies are not sent in
scan request from upper layer and default scan ies are
not sent as part of scan request sent to firmware. This
results in not including oce ie in probe requests for
framework initated scans
Fix is to copy default ies to ie field in scan request
sent to firmware.

scan request queue is accessed in multiple

For Network Listen Offload and Perfered Network Offload, the fast scan
period is multiplied by scan_backoff_multiplier after max cycles have
occurred. Expose scan_backoff_multiplier to consumers of the WMI API,
so this parameter can be configured.
