kprobes: initialize before using a hlist
commit d496aab567e7e52b3e974c9192a5de6e77dce32c upstream.
Commit ef53d9c5e ("kprobes: improve kretprobe scalability with hashed
locking") introduced a bug where we can potentially leak
kretprobe_instances since we initialize a hlist head after having used
it.
Initialize the hlist head before using it.
