double iteration list (one for registered ftrace ops, and one for
registered "global" ops), to just use one list. That simplified the code
but also broke the function tracing filtering on pid.
This updates the code to handle the filtering again with the new logic.

Pull ftrace fix from Steven Rostedt:
"Back in 3.16 the ftrace code was redesigned and cleaned up to remove
the double iteration list (one for registered ftrace ops, and one for
registered "global" ops), to just use one list. That simplified the
code but also broke the function tracing filtering on pid.
This updates the code to handle the filtering again with the new
logic"
