kprobes: Convert kprobe_exceptions_notify to use NOKPROBE_SYMBOL
commit fc62d0207ae0 ("kprobes: Introduce weak variant of
kprobe_exceptions_notify()") used the __kprobes annotation to exclude
kprobe_exceptions_notify from being probed. Since NOKPROBE_SYMBOL() is a
better way to do this enabling the symbol to be discovered as being
blacklisted, change over to using NOKPROBE_SYMBOL().
