ftrace: disable ftrace on anomalies in trace start and stop
Impact: robust feature to disable ftrace on start or stop tracing on error
Currently only the initial conversion to nops will disable ftrace
on an anomaly. But if an anomaly happens on start or stopping of the
tracer, it will silently fail.
This patch adds a check there too, to disable ftrace and warn if the
conversion fails.
