iommu/amd: Fix cleanup_domain for mass device removal

Browse source

commit 9b29d3c651 upstream.

When multiple devices are detached in __detach_device, they
are also removed from the domains dev_list. This makes it
unsafe to use list_for_each_entry_safe, as the next pointer
might also not be in the list anymore after __detach_device
returns. So just repeatedly remove the first element of the
list until it is empty.
