gfs_controld: fix lock syncing in ownership mode
    
    bz 474163
    
    Locks that are synced due to a resource being "un-owned"
    were having their read/write mode reversed on the nodes
    being synced to.  This causes the plock state on the nodes
    to become out of sync, and operate wrongly.
