P2P: Clear P2P state if active interface is disabled

The radio works for the interface get removed if interface is disabled.
This could have left P2P module in invalid state if the interface got
disabled during a p2p_find or p2p_listen operation. Clear the state in
such a case to avoid blocking following operations due to P2P module
assuming it is still in progress of doing something.
