[PATCH] Revert "irq: Add extra debugging to help track down why an assertion is failing"
This reverts commits 2ae8b9173fb2388af6514c730d620ed5f450bc34 and 98e10364bde098e12104caa4f566b17d05f8b791. This was never reported to be hit, and we assume to have taken care of the problem by excluding legacy IRQs from the IRQ move cleanup logic.
