samples/bpf: fix bpf_perf_event_output prototype
The commit 555c8a8623a3 ("bpf: avoid stack copy and use skb ctx for event output") started using 20 of initially reserved upper 32-bits of 'flags' argument in bpf_perf_event_output(). Adjust corresponding prototype in samples/bpf/bpf_helpers.h Signed-off-by: Adam Barth <arb@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: David S.
