Fix: crmd: Reset stonith failcount to recover transitioner when the node rejoins
    
    CRMd transitioner could not recover from "Too many failures to fence".
    
    Steps to produce:
    
    1. Two-node cluster with stonith, for example using IPMI.
    2. Node-1 has a complete power outage for a couple of minutes. The
    IPMI device is also without power, which causes the fencing to fail
    3. Node-2 tries to fence node-1 for several times but fails.
    4. Node-2 reports "Too many failures to fence node-1 (11), giving up".
    5. The power returns and node-1 boots up normally.
    6. Node-1 rejoins the cluster, but resources are not started on it.
    
    Expected result:
    The stonith failcount for node-1 should be reset and resources should
    be started on node-1.
    
    Actual result:
    Node-2 still logs "Too many failures to fence" and resources are not
    started on node-1.
