Simplify code by joining tcmu_cmd_get_data_length() and tcmu_cmd_get_block_cnt() into tcmu_cmd_set_block_cnts(). The new function sets tcmu_cmd->dbi_cnt and also the new field tcmu_cmd->dbi_bidi_cnt which is needed for further enhancements in following patches. Simplify some code by using tcmu_cmd->dbi(_bidi)_cnt instead of calculation from length. Please note: The calculation of the number of dbis needed for bidi was wrong. It was based on the length of the first bidi sg only. I changed it to correctly sum up entire length of all bidi sgs.

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.
