ocfs2: copy fs uuid to superblock

Currently, maximal number of cleancache enabled filesystems equals 32,
which is insufficient nowadays, because a Linux host can have hundreds
of containers on board, each of which might want its own filesystem.
This patch set targets at removing this limitation - see patch 4 for
more details.  Patches 1-3 prepare the code for this change.

This patch (of 4):

This will allow us to remove the uuid argument from
cleancache_init_shared_fs.
