console_flush_all prints all remaining records to all usable consoles whilst its caller holds console_lock. This can result in large waiting times for those waiting for console_lock especially where there is a large volume of records or where the console is slow (e.g. serial). Let's extract the parts of this function which print a single record into a new function named console_flush_one_record. This can later be used for functions that will release and reacquire console_lock between records. This commit should not change existing functionality.

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.
