nfsd4: fix seqid_mutating_error

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.
