Extra pass for subprog jit may fail (e.g. due to bpf_jit_harden race), but bpf_func is not cleared for the subprog and jit_subprogs will succeed. The running of the bpf program may lead to oops because the memory for the jited subprog image has already been freed. So fall back to interpreter mode by clearing bpf_func/jited/jited_len when extra pass fails.
