agp/intel: Fix typo in needs_ilk_vtd_wa()
In needs_ilk_vtd_wa(), we pass in the GPU device but compared it against
the ids for the mobile GPU and the mobile host bridge. That latter is
impossible and so likely was just a typo for the desktop GPU device id
(which is also buggy).
Fixes commit da88a5f7f7d434e2cde1b3e19d952e6d84533662
