nfsd: Remove incorrect check in nfsd4_validate_stateid 

commit f75546f58a 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call FREE_STATEID on the ones that have been revoked.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.

Fixes: 7df302f75e ("NFSD: TEST_STATEID should not return NFS4ERR_STALE_STATEID")
