vhost: fix message payload union in setting ring address

Browse Source 
vhost_user_set_vring_addr() uses the msg->payload.addr union member, not
msg->payload.state.  Luckily the offset of the 'index' field is
identical in both structs, so there was never any buggy behavior.

Fixes: 5cd690e4fda9 ("vhost: fix vring addresses not translated")
