Rework of the AP bus scan code. The ap_scan_bus() function is large, so this patch splits the code by introducing a new new function _ap_scan_bus_adapter() which deals with just one adapter and thus reduces the scan function code complexity. Now the AP bus scan can handle a type change of an crypto adapter on the fly (e.g. from CEX5 to CEX6). This may be the case with newer versions of zVM where the card may be pure virtual and a type change is just one click. However a type or function change requires to unregister all queue devices and the card device and re-register them. Comments around the AP bus scan code have been added and/or improved to provide some hopefully useful hints about what the code is actually doing.

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.
