In commitdee60c0dbc("s390/pci: add zpci_event_hard_deconfigured()") we added a zdev_enabled() check to what was previously an uncoditional call to zpci_disable_device(). There are two problems with that. Firstly zpci_had_deconfigured() is only called on event 0x0304 for which the device is always already disabled by the platform so it is always false. Secondly zpci_disable_device() not only disables the device but also calls zpci_dma_exit_device() which is thus not called and we leak the DMA tables. Fix this by calling zpci_disable_device() unconditionally to perform Linux side cleanup including the freeing of DMA tables.

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.
