Checking whether the memory regions are equal is sufficient: if they are equal, then most certainly the contained fd is equal. The whole vhost-user memslot handling is suboptimal and overly complicated. We shouldn't have to lookup a RAM memory regions we got notified about in vhost_user_get_mr_data() using a host pointer. But that requires a bigger rework -- especially an alternative vhost_set_mem_table() backend call that simply consumes MemoryRegionSections. For now, let's just drop vhost_backend_can_merge().
