Move the task descriptor initialization into cqhci_prep_task_desc(). In addition, make it explicitly initialize all 128 bits of the task descriptor if the host controller is using 128-bit task descriptors, rather than relying on the implicit zeroing from dmam_alloc_coherent(). This is needed to prepare for CQHCI inline encryption support, which requires 128-bit task descriptors and uses the upper 64 bits.

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.
