Manual revert of commit f598a497bc7d ("iova: Add CPU hotplug handler to
flush rcaches"). It is trying to instantiate a cpuhp notifier from inside
a cpuhp callback. That code replaced intel_iommu implementation of
flushing per-IOVA domain CPU rcaches which used a single instance of cpuhp
held for the module lifetime.
v2: Restore formerly reverted commit ac9a5d522bb8 "iommu/dma: Fix race
condition during iova_domain initialization" after we have this more
effective fix applied. The former occurred not sufficient and is no
longer needed once we have the latter in place.
Note: I'm no longer CCing IOMMU nor mainstream, they have been already
warned.
