CVE-2022-49891

In the Linux kernel, the following vulnerability has been resolved: tracing: kprobe: Fix memory leak in test_gen_kprobe/kretprobe_cmd() test_gen_kprobe_cmd() only free buf in fail path, hence buf will leak when there is no failure. Move kfree(buf) from fail path to common path to prevent the memleak.
