    sys/vfs/hammer: Temporary fix for kernel panic on volume-del
    
    This is a temporary fix for a known race issue mentioned in
    http://lists.dragonflybsd.org/pipermail/kernel/2015-August/175027.html
    
    It may be replaced with a better alternative in the future.
    
    The next commit also needs this, otherwise it's not guaranteed
    that ondisk buffers are written back to the backing storage.
    
    (cherry picked from commit 2f1df9cece2c18f660b07748af682ac3c47cc50f)
