Reduce the default VMbus channel ring buffer size for storvsc SCSI devices from 1 Mbyte to 128 Kbytes. Measurements show that ring buffer sizes above 128 Kbytes do not increase performance even at very high IOPS rates, so don't waste the memory. Also remove the dependence on PAGE_SIZE, since the ring buffer size should not change on architectures where PAGE_SIZE is not 4 Kbytes.

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.
