nfsd: fix error values returned by nfsd4_lockt() when nfsd_open() fails
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... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
