This essentially duplicates the netdev's reg_state, so just use that directly. The reg_state is updated under the rntl_lock, and all places using GOING_DOWN already acquire the rtnl_lock so checking is safe. Since the only place we use GOING_DOWN is for the parent device this does not fix any bugs, but it is a step to tidy up the unregister flow so that after later patches the flow is uniform and sane.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
