dnsdist: Fix handling of IP-only TLS certificates

To properly handle SNI with OpenSSL, we have to keep track of the TLS
names supported by the different certificates associated to a frontend.
Since IP-only names are not involved in SNI negotiations, we are currently
skipping them when creating the TLS SNI map. Unfortunately this causes
an issue when we have a single certificate that only contains IPs,
the default context not being properly set.
This commit ensures the default context is properly set in that case.

According to [MMDB_open docs], errors from `MMDB_open` should be

means that existing check never detects errors, causing further queries
to fail with error:
