qcacld-3.0: Fix to remove 11P channels from channel list during scan
qcacld-2.0 to qcacld-3.0 propagation
As per current implementation 11P channels are added to 5G band
as part of driver initialization if FEATURE_STATICALLY_ADD_11P_CHANNELS
is not defined. Kernel has enabled 11P channels due to which it gives
11p channels as part of scan command. This increases the scan time.
Add changes to remove 11P channels from the received channel list
during scan command.
