Niklas Schnelle cc049eecfb s390/pci: simplify CLP List PCI handling
Currently clp_get_state() and clp_refresh_fh() awkwardly use the
clp_list_pci() callback mechanism to find the entry for a specific FID
and update its zdev, respectively return its state.

This is both needlessly complex and means we are always going through
the entire PCI function list even if the FID has already been found.
Instead lets introduce a clp_find_pci() function to find a specific
entry and share the CLP List PCI request handling code with
clp_list_pci().

With that in place we can also easily make the function handle a simple
out parameter instead of directly altering the zdev allowing easier
access to the updated function handle by the caller.

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.
