nl80211: Handle rfkill for P2P Device interface

The rfkill processing in nl80211 driver assumes that the
INTERFACE_ENABLED/DISABLED will be also issued, so does not do much in
the rfkill callbacks. However, as a P2P Device interface is not
associated with a network interface, these events are not issued for it.

Handle rfkill events for the P2P_DEVICE interface by faking the
INTERFACE_ENABLED/DISABLED.
