vhost: predict map_guest_mem returns similar results over time
It is very likely that all packets are being stored in the same
memory area.
It is also likely that all indirect descriptors are being
allocated from the same area.
This patch takes this into account by predicting the value
returned by map_guest_mem will be the same as the previous one.
It falls back to slow mode otherwise.
