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.
