NFSv4.1: Use the more efficient open_noattr call for open-by-filehandle
When we're doing open-by-filehandle in NFSv4.1, we shouldn't need to do the cache consistency revalidation on the directory. It is therefore more efficient to just use open_noattr, which returns the file attributes, but not the directory attributes. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
