Unlike the other visit methods, visit_type_any() and visit_type_null()
neglect to check whether qmp_input_get_object() succeeded. They crash
when it fails. Reproducer:
{ "execute": "qom-set",
"arguments": { "path": "/machine", "property": "rtc-time" } }
Will crash with:
qapi/qapi-visit-core.c:277: visit_type_any: Assertion `!err != !*obj'
failed
Broken in commit 5c678ee. Fix by adding the missing error checks.
