qmp-output-visitor: Favor new visit_free() function

Browse source 
Now that we have a polymorphic visit_free(), we no longer need
qmp_output_visitor_cleanup(); however, we still need to
expose the subtype for qmp_output_get_qobject().

Backports commit 1830f22a6777cedaccd67a08f675d30f7a85ebfd from qemu
