tracing/kprobe: Make trace_kprobe's module callback called after jump_label update

Browse source

[ Upstream commit d685d55dfc ]

Make sure the trace_kprobe's module notifer callback function is called
after jump_label's callback is called. Since the trace_kprobe's callback
eventually checks jump_label address during registering new kprobe on
the loading module, jump_label must be updated before this registration
happens.
