libvhost-user: Fix VHOST_USER_GET_MAX_MEM_SLOTS reply
With REPLY_NEEDED, libvhost-user sends both the acutal result and an
additional ACK reply for VHOST_USER_GET_MAX_MEM_SLOTS. This is
incorrect, the spec mandates that it behave the same with and without
REPLY_NEEDED because it always sends a reply.
