qcacld-3.0: Disable all roam scan in case p2p connection is present

Glitches seen after the STA disconnection because of the roam scan
triggered on a heartbeat failure ( beacon miss ).STA does a partial
scan followed by full scan causing the DUT to go off-channel from
the STA and P2P home channel, causing the music BLIP.

Fix is to disable roaming irrespective of data traffic present
or not on P2P interface and enabled again once P2P is disconnected.
