Commit c1e18c17bda6 ("s390/pci: add zpci_set_irq()/zpci_clear_irq()"),
introduced the zpci_set_irq() and zpci_clear_irq(), to be used while
resetting a zPCI device.
Commit da995d538d3a ("s390/pci: implement reset_slot for hotplug slot"),
mentions zpci_clear_irq() being called in the path for zpci_hot_reset_device().
But that is not the case anymore and these functions are not called
outside of this file.
However after a CLP disable/enable reset (zpci_hot_reset_device),
the airq setup of the device will need to be restored. Since we
are no longer calling zpci_clear_airq() in the reset path, we should
restore the airq for device unconditionally.
