qcacmn: Reduce scan time when in GO+STA MCC

Browse source 
Scan on STA interface is taking around 10 secs to
complete. There is a 7secs expiry time used in nl
which could result in scan results received for
the first 3secs, which are from 2G channels, to
be flushed.

Fix is to not set offchannel simultaneous feature
capability, decrease the active dwell time for 2G
channels to 40msecs and increase burst duration
to 240msecs when GO is active.
