    Avoid panic on shutdown with memcache and INVARIANTS
    
    When running with memcache, the filesystem cache is not initialized,
    so the file-local struct vnode *volumeVnode is never set to non-NULL.
    However, shutdown_cache() unconditionally calls vrele(volumeVnode),
    which triggers a KASSERT that the argument to vrele() is non-NULL.
    For certain kernel configurations, this results in a panic.
    Change this so that vrele() is only conditionally called if the
    volumeVnode is non-NULL.
