[PATCH bpf-next] bpf: trace jit code when enable BPF_JIT_ALWAYS_ON

When CONFIG_BPF_JIT_ALWAYS_ON is enabled, the value of bpf_jit_enable in
/proc/sys is limited to SYSCTL_ONE. This is not convenient for debugging.
This patch modifies the value of extra2 (max) to 2 that support developers
to emit traces on kernel log.
