NFSv4.1 fix decode_free_stateid
The operation status is decoded in decode_op_hdr. Stop the print_overflow message that is always hit without this patch: nfs: decode_free_stateid: prematurely hit end of receive buffer. Remaining buffer length is 0 words. Signed-off-by: Andy Adamson <andros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
