tracing/ftrace: remove unused code in sched_switch tracer

Browse source

Impact: cleanup

When init_sched_switch_trace() is called, it has no reason to start
the sched tracer if the sched_ref is not zero.

_ If this is non-zero, the tracer is already used, but we can register it
to the tracing engine. There is already a security which avoid the tracer
probes not to be resgistered twice.

_ If this is zero, this block will not be used.
