qcacld-3.0: Skip ACS scan if partial scan channel not in ACS range

If determine to do partial ACS scan but partial scan channel range is
out of ACS range, sap_get_freq_list() will not return any channel list
and ACS will fail.

In this case if no additional scan needed, can skip this partial ACS
scan and continue to select channel.
