ARM: 8770/1: kprobes: Prohibit probing on optimized_callback
commit 70948c05fdde0aac32f9667856a88725c192fa40 upstream.
Prohibit probing on optimized_callback() because
it is called from kprobes itself. If we put a kprobes
on it, that will cause a recursive call loop.
Mark it NOKPROBE_SYMBOL.
Fixes: 0dc016dbd820 ("ARM: kprobes: enable OPTPROBES for ARM 32")
