qcacld-3.0: Fill primary and secondary channel in case of ACS fail

Currently the driver does not update the ACS primary channel,
and secondary channel (in case of 40, 80MHZ) in scan fail
cases or all the channels in the particular band for which ACS came
were unsafe, SRD, DFS, indoor etc., which leads to
SAP bringup fail.

Fix is to update the primary, secondary channels in case of
scan, or select channel fail.
