P2P: Move p2p_cb_on_scan_complete to global context

Browse source 
Since we have a global P2P module, the flag to trigger scan completion
events to it needs to be in similar context. The previous design
maintained this separately for each virtual interface and if P2P module
did not run its scan operation on the virtual interface that completed
the scan, P2P module would not be allowed to restart operations
properly.
