The majority of blockdev filesystems, which do not have a UUID in their
on-disk format, derive f_fsid of statfs(2) from bdev->bd_dev.
Use the same practice for freevxfs.
This will allow reporting fanotify events with fanotify_event_info_fid.

Christoph,
This is only compiled tested, but the change is quite trivial.
Could you pick up this patch? or ACK it so that Christian can take it?
Thanks,
Amir.
