[ Upstream commit 1267f7223bec186dc26ef4e6075496c6217355de ] mlxsw driver uses 'unsigned int' for reference counters in several structures. Instead, use refcount_t type which allows us to catch overflow and underflow issues. Change the type of the counters and use the appropriate API.

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.
