nfsd: Remove incorrect check in nfsd4_validate_stateid
commitf75546f58a
upstream. If the client is calling TEST_STATEID, then it is because some event occurred that requires it to check all the stateids for validity and call FREE_STATEID on the ones that have been revoked. In this case, either the stateid exists in the list of stateids associated with that nfs4_client, in which case it should be tested, or it does not. There are no additional conditions to be considered. Reported-by: "Frank Ch. Eigler" <fche@redhat.com> Fixes:7df302f75e
