Steven Rostedt e4c1a09afb tracing: Add tracer_uses_snapshot() helper to remove #ifdefs ...

Instead of having #ifdef CONFIG_TRACER_MAX_TRACE around every access to
the struct tracer's use_max_tr field, add a helper function for that
access and if CONFIG_TRACER_MAX_TRACE is not configured it just returns
false.
