Steven Rostedt (Red Hat) 989a0a3d24 tracing: Have system enable return error if one of the events fail ...

If one of the events within a system fails to enable when "1" is written
to the system "enable" file, it should return an error. Note, some events
may still be enabled, but the user should know that something did go wrong.
