s390x/pci: reject some operations to disabled PCI function

According to the s390 architecture, any mpcifc, pcilg, pcistg,
pcistb and rpcit instructions issued to disabled PCI functions
are rejected, and the instruction completes by setting condition
code 3. In addition, any DMA and MSIX interruption operations
are ignored.
