For the devices which implement the get_vq_num_min callback, the driver
should not negotiate with virtqueue size with the backend vdpa device if
the value returned by get_vq_num_min equals to the value returned by
get_vq_num_max.
This is useful for vdpa

Just failed to probe the vdpa device if the min virtqueue num returned
by get_vq_num_min is greater than the max virtqueue num returned by
get_vq_num_max.

This callback is optional. For vdpa devices that not support to change
virtqueue size, get_vq_num_min and get_vq_num_max will return the same
value, so that users can choose a correct value for that device.

Similar to previous one, this function is not implemented in this patch.
Thanks

Check vdpa device range before updating memory regions so we don't add
any outside of it, and report the invalid change if any.
