This is a cleanup patch. We don't need this reference anymore, because
blocklayout pipes dentries now creates and destroys in per-net operations and
on PipeFS mount/umount notification.
Note that nfs4blocklayout_register_net() now returns 0 instead of -ENOENT in
case of PipeFS superblock absence. This is ok, because blocklayout pipe dentry
will be created on PipeFS mount event.

This looks like a typo of some sort. The caller in
nfs4blocklayout_net_init() checks for IS_ERR(), not NULL. I'll just
remove this hunk...
Never mind. I see what's going on now... It should be NULL, and not 0
for coding style reasons, though...
Yep, NULL of course, sorry.
