The check for a matching ip prefix and subnet was only done for SMC-R in smc_listen_rdma_check() but not when an SMC-D connection was possible. Rename the function into smc_listen_prfx_check() and move its call to a place where it is called for both SMC variants. And add a new CLC DECLINE reason for the case when the IP prefix or subnet check fails so the reason for the failing SMC connection can be found out more easily.

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.
