Since commit ad739706bbadee49, user_creatable_add_type() expects to be
given a qdict. However, if object-add is called without props, you reach
the assert: "qemu/qom/object_interfaces.c:115: user_creatable_add_type:
Assertion `qdict' failed.", because the qdict isn't created in this
case (it's optional).
Furthermore, qmp_input_visitor_new() is not meant to be called without a
dict, and a further commit will assert in this situation.
If none given, create an empty qdict in qmp to avoid the
user_creatable_add_type() assert(qdict).
