We want to get rid of page->index, so let's make vsie code stop using it for the vsie page. While at it, also remove the usage of page refcount, so we can stop messing with "struct page" completely. ... of course, looking at this code after quite some years, I found some corner cases that should be fixed. Briefly sanity tested with kvm-unit-tests running inside a KVM VM, and nothing blew up.
