[PATCH 5/5] hw/virtio/virtio-pci: Remove VIRTIO_PCI_FLAG_PAGE_PER_VQ definition

[Philippe Mathieu-Daudé]

VIRTIO_PCI_FLAG_PAGE_PER_VQ was only used by the hw_compat_2_7[]
array, via the 'page-per-vq=on' property. We removed all
machines using that array, lets remove all the code around
VIRTIO_PCI_FLAG_PAGE_PER_VQ (see commit 9a4c0e220d8 for similar
VIRTIO_PCI_FLAG_* enum removal).
