Michael S. Tsirkin 46aa92d1ba vhost/net: fix heads usage of ubuf_info 
ubuf info allocator uses guest controlled head as an index,
so a malicious guest could put the same head entry in the ring twice,
and we will get two callbacks on the same value.
To fix use upend_idx which is guaranteed to be unique.
