ftrace: irqsoff tracer incorrect reset
Impact: fix to irqsoff tracer output In converting to the new start / stop ftrace handling, the irqsoff tracer start called the irqsoff reset function. irqsoff tracer is not the same as the other traces, and it resets the buffers while searching for the longest latency. The reset that the irqsoff stop method calls disables the function tracing. That means that, by starting the tracer, the function tracer is disabled incorrectly. This patch simply removes the call to reset which keeps the function tracing enabled. Reset is not needed for the irqsoff stop method.
