Replace sg_nents_for_len by sg_nents when DMA mapping/unmapping buffers and when looping over the SG entries. This fix cases where the SG entries aren't used fully, which would in such cases led to using fewer SG entries than needed (and thus the engine wouldn't have access to the full input data and the result would be wrong).

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.
