tracing: Open tracer when ftrace_dump_on_oops is used With ftrace_dump_on_oops, we previously did not open the tracer in question, sometimes causing the trace output to be useless. For example, the function_graph tracer with tracing_thresh set dumped via ftrace_dump_on_oops would show a series of '}' indented at different levels, but no function names. call trace->open() (and do a few other fixups copied from the normal dump path) to make the output more intelligible.
