[dns-client] fix handling of IPv4 resolve failure (#10766)

Browse Source 
This commit fixes an issue in `Client::ReplaceWithIp4Query()` where an
IPv6 address resolution query failure could lead to an incorrect IPv4
query being sent. The incorrect query type was being checked in this
method, causing `ResolveIp4Address()` to keep sending queries.
