iommu/amd: Fix sysfs leak in iommu init
[ Upstream commit a295ec52c8624883885396fde7b4df1a179627c3 ]
During the iommu initialization, iommu_init_pci() adds sysfs nodes.
However, these nodes aren't remove in free_iommu_resources() subsequently.
Fixes: 39ab9555c241 ("iommu: Add sysfs bindings for struct iommu_device")
