nfsd: fix error values returned by nfsd4_lockt() when nfsd_open() fails
commit 04da6e9d63427b2d0fd04766712200c250b3278f upstream.
nfsd_open() already returns an NFS error value; only vfs_test_lock()
result needs to be fed through nfserrno(). Broken by commit 55ef12
(nfsd: Ensure nfsv4 calls the underlying filesystem on LOCKT)
three years ago...
