libbpf: Remove sample_period init in perf_buffer
[ Upstream commit 64821d25f05ac468d435e61669ae745ce5a633ea ]
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.
