kprobes: fix kill kprobe which has been marked as gone
If a kprobe is marked as gone, we should not kill it again. Otherwise, we
can disarm the kprobe more than once. In that case, the statistics of
kprobe_ftrace_enabled can unbalance which can lead to that kprobe do not
work.
Fixes: e8386a0cb22f ("kprobes: support probing module __exit function")
