qmp: Don't reuse qmp visitor after grabbing output

The testsuite was the only client that attempted to reuse a
QmpOutputVisitor for a second visit after encountering an
error and/or calling qmp_output_get_qobject() on a first
visit.  The next patch is about to tighten the semantics to
be one-shot usage of the visitor, like all other visitors
(which will enable further simplifications down the road).
