virtio: pci-legacy: Validate queue pfn
Legacy PCI over virtio uses a 32bit PFN for the queue. If the
queue pfn is too large to fit in 32bits, which we could hit on
arm64 systems with 52bit physical addresses (even with 64K page
size), we simply miss out a proper link to the other side of
the queue.
Add a check to validate the PFN, rather than silently breaking
the devices.
