[PATCH] disallow kprobes on notifier_call_chain

When kprobe is re-entered, the re-entered kprobe kernel path will will call
atomic_notifier_call_chain function, if this function is kprobed that will
incur numerous kprobe recursive fault.  This patch disallows kprobes on
atomic_notifier_call_chain function.
