Commit 240f64b made all qobject input visitors created outside tests
strict, except for the one in object_property_set_qobject(). That one
was left behind only because Eric couldn't spare the time to figure
out whether making it strict would break anything, with a TODO
comment. Time to resolve it.
Strict makes a difference only for otherwise successful visits of QAPI
structs or unions. Let's examine what the callers of
object_property_set_qobject() visit:
* object_property_set_str(), object_property_set_bool(),
object_property_set_int() visit a QString, QBool, QInt,
respectively. Strictness can't matter.
* qmp_qom_set visits its @value argument. Comes straight from QMP and
can be anything ('any' in the QAPI schema). Strictness matters when
the property's set() method visits a struct or union QAPI type.
No such methods exist, thus switching to strict can't break
anything.
If we acquire such methods in the future, we'll *want* the visitor
to be strict, so that unexpected members get rejected as they should
be.
Switch to strict.
