zhangyi (F) a11e9a273a tracing: Do not free iter->trace in fail path of tracing_open_pipe() ...

commit e7f0c424d0 upstream.

Commit d716ff71dd ("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.

There's an error path that can call kfree(iter->trace) after the iter->trace
was assigned to tr->current_trace, which would be bad to free.
