Fix: crmd: abort transition whenever we lose quorum
    
    If a node drops us below quorum because it was unexpectedly lost, the peer
    update callback will abort the transition. If it was shut down cleanly while
    running resources, the CIB recovery results will abort the transition. However,
    if it was shut down cleanly while not running any resources (e.g. in standby
    mode), previously we would not trigger a new transition, and the remaining
    nodes would not stop their resources until the next recheck interval.
