Farhan Ali c9f597a4d6 vfio-ccw: Fix misleading comment when setting orb.cmd.c64
The comment is misleading because it tells us that
we should set orb.cmd.c64 before calling ccwchain_calc_length,
otherwise the function ccwchain_calc_length would return an
error. This is not completely accurate.

We want to allow an orb without cmd.c64, and this is fine
as long as the channel program does not use IDALs. But we do
want to reject any channel program that uses IDALs and does
not set the flag, which is what we do in ccwchain_calc_length.

After we have done the ccw processing, we need to set cmd.c64,
as we use IDALs for all translated channel programs.

Also for better code readability let's move the setting of
cmd.c64 within the non error path.

README

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.
