qcacmn: update SAP and P2P Go dwell time seperately

Browse source 
For SAP, the dwell time cannot exceed 32 ms as it can't go
offchannel more than 32 ms. For Go, since it advertise NOA
to annouce the absense period, it can have regular dwell
time which is 40 ms.
This was done increased scan latency was seen across
different targets.
