ftrace: disable tracing on failure
...
Since ftrace touches practically every function. If we detect any
anomaly, we want to fully disable ftrace. This patch adds code
to try shutdown ftrace as much as possible without doing any more
harm is something is detected not quite correct.
This only kills ftrace, this patch does have checks for other parts of
the tracer (irqsoff, wakeup, etc.).
