qcacmn: Set DBS scan if ndp peers are active

Browse Source 
Currently on the STA interface if the scan
comes the driver puts it to NON-DBS scan if the
high accuracy request comes, but if the NDP
peers are active this causes a throughput loss
as scan takes much time to complete.

Fix is to do a DBS scan if the NDP peers are
attached to a NDI interface.
