Instead of always treating CLP_RC_SETPCIFN_ALRDY as success and blindly updating the function handle restrict this special handling to the disable case by moving it into zpci_disable_device() and still treating it as an error while also updating the function handle such that a subsequent zpci_disable_device() succeeds or the caller can ignore the error when aborting is not an option such as for zPCI event 0x304. Also print this occurrence to the log such that an admin can tell why a disable operation returned an error. A mismatch between the state of the underlying device and our view of it can naturally happen when the device suddenly enters the error state but we haven't gotten the error notification yet, it must not happen on enable though.

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.
