Another test which now exercies the path of the verifier where it will
explore call chains rooted at the async callback. Without the prior
fixes, this program loads successfully, which is incorrect.

selftests/bpf: Add selftest for check_stack_max_depth bug2023-07-06T02:14:54+00:00Kumar Kartikeya Dwivedimemxor@gmail.com2023-07-05T14:47:30+00:00urn:sha1:906bd22a44c7c381ae92996129b075ea7beba8f6
Use the bpf_timer_set_callback helper to mark timer_cb as an async
callback, and put a direct call to timer_cb in the main subprog.
As the check_stack_max_depth happens after the do_check pass, the order
does not matter. Without the previous fix, the test passes successfully.
