In addition to the lvolstore uuid, add a per-lvol uuid for bdev
identification.
The lvol uuid is stored as an xattr for each lvol blob; if an lvol blob
without a uuid xattr is encountered, the lvol bdev will not report a
uuid for now (it will be set to all zeroes, which will be treated as
no uuid available by the generic bdev layer).
