Remove register asm usage from diag8_noresponse() since it wasn't needed at all. There is no requirement for even/odd register pairs for diag 0x8. For diag_response() use register pairs to fulfill the rx+1 and ry+1 requirements as required if a response buffer is specified. Also change the inline asm to return the condition code of the diagnose instruction and do the conditional handling of response length calculation in C.

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.
