Subject: iommu/amd: Remove local variables
Git-commit: 858defad2ae2b0ec9a0350d1414da2c2c933a054
Patch-mainline: v5.6-rc1
References: bsc#1175713

The usage of the local variables 'range' and 'misc' was removed
from commit 226e889b20a9 ("iommu/amd: Remove first/last_device handling")
and commit 23c742db2171 ("iommu/amd: Split out PCI related parts of
IOMMU initialization"). So, remove them accrodingly.
