The qmp-input visitor was playing rather fast and loose: when
visiting a QDict, you could grab members of the root dictionary
without first pushing into the dict.  But we are about to tighten
the input visitor, at which point user_creatable_add_type() MUST
follow the same paradigms as everyone else, of pushing into the
struct before grabbing its keys, because the value of 'name'
should be ignored on the top-level visit.

The change has no impact to the testsuite now, but is required to
avoid a failure in tests/test-netfilter once qmp-input is made
stricter.
