[PATCH] perf: Remove unused del_perf_probe_events

[PATCH] perf: Remove unused del_perf_probe_events

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

del_perf_probe_events() last use was removed by
commit 3d6dfae88917 ("perf parse-events: Remove BPF event support")

Remove it.

It was the last user of probe_file__del_events, so remove it as well.
