drbd: fix a race stopping the worker thread
We may implicitly call drbd_send() from inside wait_for_work(),
via maybe_send_barrier().
If the "stop" signal was send just before that, drbd_send() would call
flush_signals(), and we would run an unbounded schedule() afterwards.
Fix: check for thread_state == RUNNING before we schedule()
