relay: Avoid duplicate MetricsPort DNS error

Browse Source 
We don't output per-type DNS errors anymore so avoid looping over the
DNS query type and output each errors for them. Before this commit, it
created 3x the same message because we had A, AAAA and PTR type records.

Fix on previous commit e7abab8782
