qcacld-3.0: Avoid channel 12, 13 for SAP operation

Currently the driver selects channel 12, 13 as they are
free from BSS as their weights are minimum, which results
into IOT issues as legacy STAs do not support the same.

Fix is to avoid channel 12, 13 in SAP ACS process, and try
to start the SAP on channels from 1 - 11.
