qcacld-3.0: Cancel Remain on channel command before stop ap

Browse source 
qcacld-2.0 to qcacld-3.0 propagation

If P2P-GO stop comes during ROC, it may cause WLANSAP_StopBss
API to fail. ROC is stuck as firmware is running Gscan which
is higher priority than p2p ROC scan prioirty.
This causes ROC command to be stuck in the active list for 10
seconds and will eventually cause a crash in FW when host will
try to add self peer since older peer is still present in the
FW with same mac address

Add change to increase the priority of P2P scan and cancel ROC
before calling stop AP API.
