qcacld-3.0: Select default channel is no scan results present

Currently if the driver does not find any scan results
in the ACS scan, it selects a best channel as the PCl
channel by filtering the PCl list based upon the start
and end channel, which may not be correct everytime
as start and end channel does not specify the channels
to be selected.

Fix is to select a default operating channel from the
acs list itself, if no scan results are present.
