bpf,perf: Fix perf_event_detach_bpf_prog error handling
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: 170a7e3ea070 ("bpf: bpf_prog_array_copy() should return -ENOENT if exclude_prog not found")
