tracing/ftrace: fix unexpected -EINVAL when longest tracer name is set

Impact: fix confusing write() -EINVAL when changing the tracer

The following commit d9e540762f5cdd89f24e518ad1fd31142d0b9726 remade
alive the bug which made the set of a new tracer returning -EINVAL if
this is the longest name of tracer. This patch corrects it.
