drm/xe: Fix GT looping for standalone media

gt_count is only being incremented when initializing the primary GT;
since the media GT sets the ID directly, gt_count is not incremented
again, resulting in an incorrect count on MTL.  Use autoincrement while
assigning the media GTs ID to ensure gt_count is correct on MTL and
other future platforms with standalone media.
