Allow those who hold implicit reference on a devlink instance to try to take a full ref on it. This will be used from netdev code which has an implicit ref because of driver call ordering. Note that after recent changes devlink_unregister() may happen before netdev unregister, but devlink_free() should still happen after, so we are safe to try, but we can't just refcount_inc() and assume it's not zero.

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.
