dhcpv6: Reject empty messages

The uio library doesn't report errors on a per-operation basis, but
accumulates them so they can be checked after a batch of operations in a
separate Error() function. Unfortunately this makes it easy to forget,
thus parse incorrect messages

go-fuzz found immediately that an empty message would be parsed without
error, and reserialize to a different message (one with some bytes of
zeros)
