qcacmn: Fix scan policy type in default scan case

The driver has a default scan policy type of DBS scan
which is not overwritten in case of DBS disabled.

Fix is to have a default of NON-DBS scan, and overwrite the
scan policy if the low power, low span scan is triggered,
or if the DBS is disabled from ini.
