net/sched: Retire tcindex classifier

commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28 upstream.

The tcindex classifier has served us well for about a quarter of a century
but has not been getting much TLC due to lack of known users. Most recently
it has become easy prey to syzkaller. For this reason, we are retiring it.
