P2P: Continue P2P_WAIT_PEER_(IDLE/CONNECT) sequence on a listen cancel

Browse source 
Some drivers may accept the remain-on-channel command, but instead of
indicating start event for remain-on-channel, just indicate that the
operation has been canceled immediately. This listen cancel from the
WAIT_PEER_CONNECT state ended up in discontinuation of further
WAIT_PEER_IDLE/WAIT_PEER_CONNECT state transitions. Hence, delay the
subsequent IDLE state by 100 ms.
