[PATCH] nfsd4: remove release_state_owner()

It's confusing having both release_stateowner() and release_state_owner().

And as it turns out, release_state_owner() is short and only called from one
place; so just remove it.

Also note the confirmed check is superfluous there--preprocess_seqid_op
already check this.

And remove a redundant comment and a superfluous line assignment while we're
at it.
