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 127c761598 ("iommu/vt-d:
Pass device_domain_info to __dmar_remove_one_dev_info").
