virtio-pci: reduce modern_mem_bar size
Currently each VQ Notification Virtio Capability is allocated
on a different page. The idea is to enable split drivers within
guests, however there are no known plans to do that.
The allocation will result in a 8MB BAR, more than various
guest firmwares pre-allocates for PCI Bridges hotplug process.
Reserve 4 bytes per VQ by default and add a new parameter
"page-per-vq" to be used with split drivers.
