tracing: branch: Use trace_tracing_is_on_cpu() instead of "disabled" field

Browse Source 
The branch tracer currently checks the per CPU "disabled" field to know if
tracing is enabled or not for the CPU. As the "disabled" value is not used
anymore to turn of tracing generically, use tracing_tracer_is_on_cpu()
instead.
