qcacmn: Allow DBS scan if enabled in ini

Currently the driver checks that DBS for connection
is allowed or not, and on that basis rejects the scan,
but it may happen that FW supports DBS, and DBS for
scan is enabled in the ini, but the DBS for connection
is disabled.
In that case the diver opts for non-dbs scan.

Fix is to allow DBS scan in case of DBS scan enabled in ini.
