ftrace: disable tracing when current_tracer is set to "none"

Browse source

Found that inspite of setting the current_tracer to "none", trace from
the previous trace type continued to be collected. The patch below fixes
this and causes the trace to be disabled when the "none" type is
selected.

Compile and boot tested the patch for functionality.
