    VGetVolume_r: do not wait for offlining volumes
    
    In VGetVolume_r, previously we waited for a volume with
    vp->goingOffline set to go offline before we return. However, the
    fileserver afsfileprocs.c case can treat the "going offline" case and
    the "is offline" case identically, so there is no reason to wait. So
    make the fileserver call a new GetVolume variant that does not wait.
    
    Without this, all of the threads in the fileserver can potentially be
    tied up by waiting for a volume to go offline, if the volume is taking
    a long time to go offline due to an offline request following a client
    slowly accessing the volume.
