tracing: Use RING_BUFFER_ALL_CPUS for TRACE_PIPE_ALL_CPU
Both RING_BUFFER_ALL_CPUS and TRACE_PIPE_ALL_CPU are defined as -1 and used to say that all the ring buffers are to be modified or read (instead of just a single cpu, which would be >= 0). There's no reason to keep TRACE_PIPE_ALL_CPU as it is also started to be used for more than what it was created for, and now that the ring buffer code added a generic RING_BUFFER_ALL_CPUS define, we can clean up the trace code to use that instead and remove the TRACE_PIPE_ALL_CPU macro.
