Jiri Olsa 7a5c653ede bpf,perf: Fix perf_event_detach_bpf_prog error handling 
[ Upstream commit 0ee288e69d033850bc87abe0f9cc3ada24763d7f ]

Peter reported that perf_event_detach_bpf_prog might skip to release
the bpf program for -ENOENT error from bpf_prog_array_copy.

This can't happen because bpf program is stored in perf event and is
detached and released only when perf event is freed.

Let's drop the -ENOENT check and make sure the bpf program is released
in any case.

Fixes: 170a7e3ea0 ("bpf: bpf_prog_array_copy() should return -ENOENT if exclude_prog not found")
