x86/amd-iommu: Fix crash when request_mem_region fails When request_mem_region fails the error path tries to disable the IOMMUs. This accesses the mmio-region which was not allocated leading to a kernel crash. This patch fixes the issue. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
