Subject: [PATCH] Revert "QDbus: Avoid memory leak in registerComplexDBusType"

This reverts commit 4c1df115ecfb14c353c0ec46efdb1f9d2fc0ea95.

We cannot guarantee that there are no more QMetaType
instances that reference the interfaces being destroyed.
All such instances will become invalid after the interface
destruction with no way to verify that.
