    Prevent crash on Windows when data version goes backwards
    
    Within cm_MergeStatus() cm_FindVolumeByID() was called with
    a NULL pointer instead of a valid cm_req_t object pointer
    in the case where the data version for an object received
    from the file server is smaller than the value already stored
    in the cache.   This results in a NULL pointer dereference.
    
    Allocate a cm_req_t object on the stack and initialize it
    before calling cm_FindVolumeByID() in this case.
