qcacld-3.0: Do DFS flag configure only when DFS channels are supported

Browse source 
When gEnableDFSChnlScan is configured as 0, it is incorrect that DFS
channels are not skipped when scanning.
Android O/P framework always enables DFS flag for station interface, then
gEnableDFSChnlScan is always overwritten currently.

Only support DFS flag configuration when gEnableDFSChnlScan is set as 1.
