When running a disconnect torture test I noticed that sometimes we would crash with a negative ref count on our queue. This was because we were ending the same request twice. Turns out we were racing with NBD_CLEAR_SOCK clearing the requests as well as the teardown of the device clearing the requests. So instead make the ioctl only shutdown the sockets and make it so that we only ever run nbd_clear_que from the device teardown.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
