gfs2: fs: derive f_fsid from s_uuid
gfs2 already has optional persistent uuid.
Use that uuid to report f_fsid in statfs(2), same as ext2/ext4/zonefs.
This allows gfs2 to be monitored by fanotify filesystem watch.
for example, with inotify-tools 4.23.8.0, the following command can be
used to watch changes over entire filesystem:
fsnotifywatch --filesystem /mnt/gfs2
