Fixes gcc '-Wunused-but-set-variable' warning:

drivers/iommu/amd_iommu.c: In function 'amd_iommu_uninit_device':
drivers/iommu/amd_iommu.c:422:20: warning:
 variable 'iommu' set but not used [-Wunused-but-set-variable]

commit dce8d6964ebd ("iommu/amd: Convert to probe/release_device() call-backs")
involved this, remove it.
