Although this code should raise an overflow error, it didn't because check_recursion_limit it checks for depth = 128 but not for 129 which should have triggered the overflow error. Anyways this catches that error early.

Fixes #95134

I don't understand why this check needs to be performed in this specific place but not in others.
Perhaps someone else is more familiar with this code.

There is a similar check above, so I thought it was appropriate to put it here 😅

Reverts check done by rust-lang#100757

As my `fix` caused more issues than it resolved it's better to revert it.
