    vol: Do not give back not-checked-out vols
    
    VAttachVolumeByName_r has logic to give back a volume over FSSYNC if
    we checked out a volume but failed to attach it for whatever reason.
    However, the logic used for determining if the volume was checked out
    or not is a bit inaccurate (even moreso than the comments imply),
    potentially causing us to VOL_ON volumes that don't exist at all.
    
    Instead of trying to guess based on various conditions whether or not
    we checked out the volume, keep track of a variable that is only set
    when we actually checkout the volume from the fileserver. Then only
    give back the volume if it is set.
