Despite allocating and providing code to handle accesses to the pba structure, virtio msix blocks in fact only register the msix table with kvm. This patch fixes the MMIO region so that it includes the pba structure for msix io blocks of virtio pci devices. The corresponding BAR is also updated to advertise the full size of the io block.
