iommu/vt-d: Remove set but not used variable
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/iommu/intel/iommu.c:5643:27: warning: variable 'last_pfn' set but not used [-Wunused-but-set-variable]
5643 | unsigned long start_pfn, last_pfn;
| ^~~~~~~~
This variable is never used, so remove it.
Fixes: 2a2b8eaa5b25 ("iommu: Handle freelists when using deferred flushing in iommu drivers")
