i965: Only emit VF cache invalidations when the high bits changes
Commit 92f01fc5f914 ("i965: Emit VF cache invalidates for 48-bit
addressing bugs with softpin.") tried to only emit the VF invalidate if
the high bits changed, but it accidentally always set need_invalidate to
true; causing it to emit unconditionally emit the pipe control before
every primitive.
Fixes: 92f01fc5f914 ("i965: Emit VF cache invalidates for 48-bit addressing
bugs with softpin.")
