iommu/vt-d: Fix misplaced domain_attached assignment

Commit fb5873b ("iommu/vt-d: Restore context entry setup order
for aliased devices") was incorrectly backported: the domain_attached
assignment was mistakenly placed in device_set_dirty_tracking()
instead of original identity_domain_attach_dev().

Fix this by moving the assignment to the correct function as in the
original commit.
