tracing: Have branch tracer use trace_handle_return() helper function
The branch tracer should not be checking the trace_seq_printf() return value as that will soon be void. There's a new trace_handle_return() helper function that will return TRACE_TYPE_PARTIAL_LINE if the trace_seq overflowed and TRACE_TYPE_HANDLED otherwise.
