If the queue pfn is too large to fit in 32bits, which

virtio-mmio with virtio-v1 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,
