vfio-pci: Fix possible integer overflow
The VFIO_DEVICE_SET_IRQS ioctl takes a start and count parameter, both
of which are unsigned. We attempt to bounds check these, but fail to
account for the case where start is a very large number, allowing
start + count to wrap back into the valid range. Bounds check both
start and start + count.
