We only need to test for these counters being non-zero when we see the end of a transfer. If we're doing a CS change then they will already be zero. This implies that we don't need to set these to 0 if we're cancelling an in flight transfer too, because we only care to test these counters when the 'DONE' bit is set in the hardware and we've set them to non-zero for a transfer. This is a non-functional change, just cleanup to consolidate code.

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.
