When messages are received via tipc socket under non-block mode, schedule_timeout() is called in tipc_wait_for_rcvmsg(), that is, the process of receiving messages will be scheduled once although timeout value passed to schedule_timeout() is 0. The same issue exists in accept()/wait_for_accept(). To avoid this unnecessary process switch, we only call schedule_timeout() if the timeout value is non-zero.
