MINOR: resolvers: Directly call srvrq_update_srv_state() when possible

When the server status must be updated from the result of a SRV resolution,
we can directly call srvrq_update_srv_state(). It is simpler and this avoid
a test on the server DNS resolution.

This patch is mandatory for the next commit. It also rely on "MINOR:
