libbpf: Remove sample_period init in perf_buffer
It seems that sample_period is not used in perf buffer. Actually, only
wakeup_events are meaningful to enable events aggregation for wakeup notification.
Remove sample_period setting code to avoid confusion.
Fixes: fb84b8224655 ("libbpf: add perf buffer API")
