x86/amd-iommu: Use helper function to destroy domain
commit 8b408fe4f853dcfa18d133aa4cf1d7546b4c3870 upstream.
In the amd_iommu_domain_destroy the protection_domain_free
function is partly reimplemented. The 'partly' is the bug
here because the domain is not deleted from the domain list.
This results in use-after-free errors and data-corruption.
Fix it by just using protection_domain_free instead.
