    Windows: VolumeCB->ObjectInfoTree.TreeLock Deadlock
    
    AFSPrimaryVolumeWorkerThread held the VolumeCB->ObjectInfoTree.TreeLock
    exclusively across calls to AFSCleanupFcb() which in turn triggers
    a file extent release to the service which can in turn result in
    an object invalidation.  Processing the invalidation requires shared
    access to VolumeCB->ObjectInfoTree.TreeLock which results in a deadlock.
    
    This patch alters the processing of AFSPrimaryVolumeWorkerThread
    so that the VolumeCB->ObjectInfoTree.TreeLock is not held across
    the AFSCleanupFcb() calls.
    
    FIXES 130431
