dnsdist: Check that cached responses are >= sizeof(dnsheader)

The check is done before inserting the response into the cache, but
it feels safer to check it again before passing it to `memcpy()`.
We check that the cached response is larger than
`sizeof(dnsheader) + qname` afterwards, but the previous commit
moved the header copy before that check.
