iommu/vt-d: Remove domain parameter for intel_pasid_setup_dirty_tracking()
The only usage of input @domain is to get the domain id (DID) to flush cache after setting dirty tracking. However, DID can be obtained from the pasid entry. So no need to pass in domain. This can make this helper cleaner when adding the missing dirty tracking for the parent domain, which needs to use the DID of nested domain.
