simpleperf: use ioctl to get event fd id. Currently EventFd uses read() to get id. But it is affected by event_attr.read_format, which will change based on record options. So switch to get id via ioctl. Bug: 211001523 Test: run simpleperf_unit_test Change-Id: I4beb9865e357aa77c2522d5a2688b925cbb793e2
