Oleg Nesterov cd92bf61d6 tracing/perf: Move the PERF_MAX_TRACE_SIZE check into perf_trace_buf_prepare() 
Every perf_trace_buf_prepare() caller does
WARN_ONCE(size > PERF_MAX_TRACE_SIZE, message) and "message" is
almost the same.

Shift this WARN_ONCE() into perf_trace_buf_prepare(). This changes
the meaning of _ONCE, but I think this is fine.
