conn_try_disconnect() could potentialy hit the BUG_ON() in _conn_set_state() where it iterates over _drbd_set_state() and "asserts" via BUG_ON() that the latter was successful. If the STATE_SENT bit was not yet visible to conn_is_valid_transition() early in _conn_request_state(), but became visible before conn_set_state() later in that call path, we could hit the BUG_ON() after _drbd_set_state(), because it returned SS_IN_TRANSIENT_STATE. To avoid that race, we better protect set_bit(SENT_STATE) with the spinlock.
