qcacld-3.0: Remove 11P channels from channel list in PNO scan

qcacld-2.0 to qcacld-3.0 propagation

Host driver receives 11P channels as part of PNO scan because
kernel enables 11P channels. This increases the scan time.

Add changes to remove 11P channels from the received
channel list in PNO scan
