File Import-ID_FS_XXX-variables-bnc909358.patch of Package lvm2.1626

Subject: [PATCH] 13-dm-disk.rules: Import ID_FS_XXX variables from udev
         database
References: bnc#909358

If the disk is unavailable we need to import the existing ID_FS_XXX
variables from the database, otherwise the filesystem UUID won't
be set and the by-uuid symlink will disappear, leading to
intermittent boot failures.
