Revert "xsk: simplify AF_XDP socket teardown"
This reverts commit e2ce3674883ecba2605370404208c9d4a07ae1c3. It turns out that the sock destructor xsk_destruct was needed after all. The cleanup simplification broke the skb transmit cleanup path, due to that the umem was prematurely destroyed. The umem cannot be destroyed until all outstanding skbs are freed, which means that we cannot remove the umem until the sk_destruct has been called.

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.
