commit a060c1f12b525ba828f871eff3127dabf8daa1e6 upstream.
The help info of option "--no-bpf-event" is wrongly described as "record bpf events", correct it.
Committer testing:
$ perf record -h bpf
Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>]
--clang-opt <clang options> options passed to clang when compiling BPF scriptlets --clang-path <clang path> clang binary to use for compiling BPF scriptlets --no-bpf-event do not record bpf events
$
