(finally) fix #1099: return disklist correctly

in get_disks, when called with a parameter 'cciss/cXdY', we replaced
the '/' with '!' so that we can properly poll the information
about it from /sys/block/

but we have to replace the '!' with '/' again in our result list,
because the caller does not know anything about it and fails, because
the original dev is not in the list
