Creating and opening the GuC log relay file enables and starts the relay potentially before the caller is ready to consume logs. Change the behavior so that relay starts only on an explicit call to the write function (with a value of '1'). Other values flush the log relay as before. v2: Style changes and fix typos. Add guc_log_relay_stop() function.

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 Restructured Text 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.
