Steven Rostedt (VMware) 26dda5631d ftrace: Allow function_graph tracer to be enabled in instances 
Now that function graph tracing can handle more than one user, allow it to
be enabled in the ftrace instances. Note, the filtering of the functions is
still joined by the top level set_ftrace_filter and friends, as well as the
graph and nograph files.
