* fhandler_socket.cc (fhandler_socket::af_local_connect): Drop

setting connect_state to connect_credxchg.
	(fhandler_socket::af_local_accept): Ditto.
	(fhandler_socket::recv_internal): Drop ill-advised connect_state check.
	Add comment so as not to repeat the exercise.
	* fhandler.h (enum conn_state): Drop now unneeded connect_credxchg
	state.
