Masami Hiramatsu (Google) 23c0e9cc76 tracing: Show the tracer options in boot-time created instance
Since tracer_init_tracefs_work_func() only updates the tracer options
for the global_trace, the instances created by the kernel cmdline
do not have those options.

Fix to update tracer options for those boot-time created instances
to show those options.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
