iommu/amd: Remove local variables

Browse source 
The usage of the local variables 'range' and 'misc' was removed
from commit 226e889b20 ("iommu/amd: Remove first/last_device handling")
and commit 23c742db21 ("iommu/amd: Split out PCI related parts of
IOMMU initialization"). So, remove them accrodingly.
