iommu/vt-d: Remove unused dmar_remove_one_dev_info() argument
domain_remove_dev_info() takes a struct dmar_domain * argument, but doesn't use it. Remove it. No functional change intended. The last use of this argument was removed by 127c761598f7 ("iommu/vt-d: Pass device_domain_info to __dmar_remove_one_dev_info").
