tracing: Make tracer_tracing_is_on() return bool
There's code that expects tracer_tracing_is_on() to be either true or false, not some random number. Currently, it should only return one or zero, but just in case, change its return value to bool, to enforce it. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
