P2P: Avoid truncation of long listen operation due to offchan tx

On receiving the cancel remain on channel event, the pending_tx
is scheduled immediately and returned. This was preventing
the wpas_p2p_listen_start function from execution thereby resulting
in termination of the long listen operation.
