Commit d716ff71dd12 ("tracing: Remove taking of trace_types_lock in
pipe files") use the current tracer instead of the copy in
tracing_open_pipe(), but it forget to remove the freeing sentence in
the error path.
[ Note, this is harmless because kfree(NULL) is allowed and iter is
allocated with kzalloc() making iter->trace = NULL -- S. Rostedt ]
