qom: Avoid leaking str and bool properties on failure
When object_property_add_str() and object_property_add_bool() fail, they
leak their internal StringProperty and BoolProperty structs. Remember
to free the structs on error.
Luckily this is a low-impact memory leak since most QOM properties are
static qdev properties that will never take the error case.
object_property_add() only fails if the property name is already in use.
