Subject: [PATCH 006 of 20] knfsd: nfsd: remove superfluous assignment from nfsd_lookup


From: J. Bruce Fields <bfields@...i.umich.edu>

The "err" variable will only be used in the final return, which always
happens after either the preceding

	err = fh_compose(...);

or after the following

	err = nfserrno(host_err);

So the earlier assignment to err is ignored.
