Subject[34-longterm 102/247] nfsd: correctly handle return value from nfsd_map_name_to_*
Date
From: NeilBrown <neilb@suse.de>

-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
If you see a problem with using this for longterm, please comment.
-------------------

commit 47c85291d3dd1a51501555000b90f8e281a0458e upstream.

These functions return an nfs status, not a host_err. So don't
try to convert before returning.

This is a regression introduced by
3c726023402a2f3b28f49b9d90ebf9e71151157d; I fixed up two of the callers,
but missed these two.
