Trond Myklebust 61b287aa88 NFSv4: OPEN must handle the NFS4ERR_IO return code correctly ...

commit c7848f69ec 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.
