Current buffer handling logic fails in a case where the buffer contains existing data from previous update which is divisible by block size. This results in a block size of data to be left missing from the sg list going out to the hw accelerator, ending up in stalling the crypto accelerator driver (the last request never completes fully due to missing data.) Fix this by passing the total size of the data instead of the data size of current request, and also parsing the buffer contents within the prepare request handling.

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.
