Subject: [PATCH] dm: Fix comparing DM RAID member devices UUID

There is no "UUID" property in UDev we must use the "ID_FS_UUID"
one.
This comparison works only because most DM RAID members don't have
UUID so the check is skipped, but it fails for DDF RAID members
which have a special GUID/UUID in UDev database.
