iommu/amd: Remove local variables
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. Signed-off-by: Adrian Huang <ahuang12@lenovo.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
