Receive and send buffer allocation was originally introduced to support DPDK's networking use case. These buffer sizes were further increased to meet DPDK performance requirements. However, these large buffers are unnecessary for any other UIO use cases. Restrict the allocation of receive and send buffers only for HV_NIC device type, saving 47 MB of memory per device. While at it, fix some of the syntax related issues in the touched code which are reported by "--strict" option of checkpatch.

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 reStructuredText 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.
