[PATCH v2] vhost-vdpa: Remove redundant declaration of address_space_memory

[Xie Yongji <xieyongji@bytedance.com>]

The symbol address_space_memory are already declared in
include/exec/address-spaces.h. So let's add this header file
and remove the redundant declaration in include/hw/virtio/vhost-vdpa.h.
