qcacmn: Change burst_duration and min_rest_time value

Browse source 
Enable burst scan for GO+STA case and set the burst
duration as 1 active dwell time.
Burst scan provides higher priority and can ensure
the scan request granted, since P2P GO requests larger
duration for its high priority channel request.
But this value will limit the off-channel time to give
more bandwidth for P2P home channel.
Also, change minimum rest time from 50 to max rest time
i.e. 100 for MCC case for all concurrency combinations.
50ms min reset time only grants 1 home channel in MCC,
when there is only 1 home channel and has heavy traffic,
it can be scheduled firstly as scan BSS channel, and if
activity check found not much traffic for the 1st 50ms,
it decides to go foreign channel directly, the 2nd home
channel with heavy traffic will not get chance to schedule.
