Philipp Reisner c1fd29a11f drbd: Fix a race condition that can lead to a BUG() ...

If the preconditions for a state change change after the wait_event() we
might hit the BUG() statement in conn_set_state().

With holding the spin_lock while evaluating the condition AND until the
actual state change we ensure the the preconditions can not change anymore.
