iommu/vt-d: Remove device comparison in context_setup_pass_through_cb
commit 64f792981e35e191eb619f6f2fefab76cc7d6112 upstream.
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.
Fixes: 2031c469f816 ("iommu/vt-d: Add support for static identity domain")
Closes: https://lore.kernel.org/linux-iommu/82499eb6-00b7-4f83-879a-e97b4144f576@linux.intel.com/
