[Libguestfs] [libnbd PATCH v2 1/6] states: Tweak comment in OPT_GO state handler
While auditing code, I stumbled across a confusing comment which
references a state name that does not exist. In addition to improving
the comment, I added an assertion, since there is action at a distance
(prepare_for_reply_payload is in states-newstyle.c) for ignoring the
oversized payload.
