vfio/pci: Stub vfio_pci_vga_rw when !CONFIG_VFIO_PCI_VGA
Resolve build errors reported against UML build for undefined
ioport_map() and ioport_unmap() functions. Without this config
option a device cannot have vfio_pci_core_device.has_vga set,
so the existing function would always return -EINVAL anyway.
