Danilo Krummrich fde40a558d rust: usb: fix broken call to T::disconnect()
A refactoring of Device::drvdata_obtain() broke T::disconnect() in the
USB abstractions.

"""

This slipped through, since the USB abstractions are globally disabled.
However, the USB tree recently enabled them, hence it showed up in
linux-next.

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 reStructuredText 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.
