Steven Rostedt (Google) f5ca233e2e tracing: Increase trace array ref count on enable and filter files 
When the trace event enable and filter files are opened, increment the
trace array ref counter, otherwise they can be accessed when the trace
array is being deleted. The ref counter keeps the trace array from being
deleted while those files are opened.
