i965: Fix GS state uploading on Sandybridge
Need to check the required primitive type for GS on Sandybridge,
and when GS is disabled, the new state has to be issued too, instead
of only updating URB state with no GS entry, that caused hang on Sandybridge.
This fixes hang issue during conformance suite testing.
