Steven Rostedt (Google) 9b65bff30a tracing: Have event inject files inc the trace array ref count
[ Upstream commit e5c624f027ac74f97e97c8f36c69228ac9f1102d ]

The event inject files add events for a specific trace array. For an
instance, if the file is opened and the instance is deleted, reading or
writing to the file will cause a use after free.

Up the ref count of the trace_array when a event inject file is opened.
