bpf: fix maximum stack depth tracking logic
Instead of computing max stack depth for current call chain
during the main verifier pass track stack depth of each
function independently and after do_check() is done do
another pass over all instructions analyzing depth
of all possible call stacks.
Fixes: f4d7e40a5b71 ("bpf: introduce function calls (verification)")
