nfsd4: look up stateid's per clientid
Use a separate stateid idr per client, and lookup a stateid by first finding the client, then looking up the stateid relative to that client. Also some minor refactoring. This allows us to improve error returns: we can return expired when the clientid is not found and bad_stateid when the clientid is found but not the stateid, as opposed to returning expired for both cases. I hope this will also help to replace the state lock mostly by a per-client lock, but that hasn't been done yet. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
