Subject[093/262] nfsd4: fix seqid_mutating_error
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------
From: "J. Bruce Fields" <bfields@redhat.com>

commit 576163005de286bbd418fcb99cfd0971523a0c6d upstream.

The set of errors here does *not* agree with the set of errors specified
in the rfc!

While we're there, turn this macros into a function, for the usual
reasons, and move it to the one place where it's actually used.

Signed-off-by: J. Bruce Fields <bfields@redhat.com>
