qcacld-3.0: Correct the p2p scan parameters when SAP is beaconing

Browse source 
Correct the p2p scan's active dwell time, passive dwell time and
burst duration when a SAP session is already active. Since the
max duration of CTS-to-self is 32ms, the dwell time for p2p scans
are calculated in such a way that it does not cross 32ms if SAP
is running. This is in line with the existing STA scan parameters
when SAP is active.
