[PATCH 10/14] dns: poll card between each dns request

[Josef Bacik]

If we have dns servers that we prefer to get AAAA records from we'll send a
packet and immediately check data.naddresses to see if we got a response.  If we
didn't we'll then send a request for an A record, and _then_ we'll poll the
card.  So if the DNS server doesn't respond between us sending the packet and
checking data.naddresses we'll send a request for the A record and then poll the
card.  Instead we need to make sure we poll after we issue each request to make
sure we give the server enough time to respond to our initial request.
