qcacld-3.0: Avoid beacon parsing on channels not in scan list for ACS

Browse source 
When STA is already up on some 2.4Ghz channel and SAP needs to be started
on some 5Ghz channel through ACS, scan channel list contains only 5Ghz
channels. But scan results contains beacons on STA 2.4Ghz channel as well
which is getting parsed contributing to bsscount and rssi on that 2.4Ghz
channel which should not be the scenario as bsscount should be 0 and rssi
should be -100 on this 2.4Ghz channel as it is not present in the scan
channel list sent by HOST to fw.

Avoid beacon parsing on all the channels other than the channels present
in ACS scan channel list.
