vfs: Re-introduce s_uuid in the superblock
Gaah. When commit be85bccaa5aa reverted the export of file system uuid
via /proc/<pid>/mountinfo, it also unintentionally removed the s_uuid
field in struct super_block.
I didn't mean to do that, since filesystems have been taught to fill it
in (and we want to keep it for future re-introduction in the mountinfo
file).
Stupid of me. This adds it back in.
