x86/amd-iommu: Un__init function required on shutdown commit ca0207114f1708b563f510b7781a360ec5b98359 upstream. The function iommu_feature_disable is required on system shutdown to disable the IOMMU but it is marked as __init. This may result in a panic if the memory is reused. This patch fixes this bug.
