Muchun Song d44a437826 kprobes: fix kill kprobe which has been marked as gone 
[ Upstream commit b0399092cc ]

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: e8386a0cb2 ("kprobes: support probing module __exit function")
