libvhost-user: add vmsg_set_reply_u64() helper
The VhostUserMsg request is reused as the reply by message processing
functions. This is risky since request fields may corrupt the reply if
the vhost-user message handler function forgets to re-initialize them.
Changing this practice would be very invasive but we can introduce a
helper function to make u64 payload replies safe. This also eliminates
code duplication in message processing functions.
