[PATCH v3 05/34] tests/test-qmp-cmds: Factor out qmp_dispatch() test helpers

[Markus Armbruster <armbru@redhat.com>]

Checking the value of qmp_dispatch() is repetitive.  Factor out
helpers do_qmp_dispatch() and do_qmp_dispatch_error().  Without this,
the next commit would make things even more repetitive.
