Subject: [PATCH] [126/275] nfsd: correctly handle return value from nfsd_map_name_to_*

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: NeilBrown <neilb@...e.de>

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.
