    Ignore drives without volumes
    
    This fixes a problem on some dmraid setups where we have drives
    without any partitions (the dmraid boot scripts removes all partitions
    (!)). See https://bugzilla.redhat.com/show_bug.cgi?id=495152 for more
    details.
    
    This fix is also consistent with the policy of ignoring drives where
    all volumes are ignored. E.g. prior to this patch we didn't shown
    neither sdb if sdb1 was a the only unrecognized partition on sdb.. so
    if you delete sdb1, it would be natural to keep hiding sdb (which is
    what this patch does).
