Peter Zijlstra 51c695986f perf: Ensure bpf_perf_link path is properly serialized ...

[ Upstream commit 7ed9138a72829d2035ecbd8dbd35b1bc3c137c40 ]

Ravi reported that the bpf_perf_link_attach() usage of
perf_event_set_bpf_prog() is not serialized by ctx->mutex, unlike the
PERF_EVENT_IOC_SET_BPF case.
