kprobes: Prevent re-registration of the same kprobe
Prevent re-registration of the same kprobe. This situation, though unlikely, needs to be flagged since it can lead to a system crash if it's not handled. The core change itself is small, but the helper routine needed to be moved around a bit; hence the diffstat.
