    gluster/uss: Handle notify in snapview-client

    As there are two subvolumes in snapview-client, there is
    a possibility that the regular subvolume is still down and
    snapd subvolume come up first. So if we don't handle this situation
    CHILD_UP event will be propagated upwards to fuse when regular subvolume
    is still down. This can cause data unavailable for the application
