Stefan Eichenberger e4b5f41539 usb: core: replace usb_sndaddr0pipe macro with usb_sndctrlpipe
The usb_sndaddr0pipe macro is only used in the hub_set_address function.
Replace it with usb_sndctrlpipe which provides the same functionality
but would also consider the endpoint device number.

If the device has not been initialised, it is safe to use
usb_sndctrlpipe in this context because udev->devnum is set to 0.
Therefore, this change does not affect behaviour, but reduces code
complexity by reusing the existing macro.

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.
