NFSv4: OPEN must handle the NFS4ERR_IO return code correctly

commit c7848f69ec4a8c03732cde5c949bd2aa711a9f4b upstream.

decode_op_hdr() cannot distinguish between an XDR decoding error and
the perfectly valid errorcode NFS4ERR_IO. This is normally not a
problem, but for the particular case of OPEN, we need to be able
to increment the NFSv4 open sequence id when the server returns
a valid response.
