iommu/vt-d: Remove device comparison in context_setup_pass_through_cb

commit 64f7929

Remove the device comparison check in context_setup_pass_through_cb.
pci_for_each_dma_alias already makes a decision on whether the
callback function should be called for a device. With the check
in place it will fail to create context entries for aliases as
it walks up to the root bus.
