BUG/MINOR: resolvers: Unlink DNS resolution to set RMAINT on SRV resolution
When a server is set in RMAINT becaues of a SRV resolution failure, the
server DNS resolution, if any, must be unlink first. It is mandatory to
handle the change in the context of a SRV resolution.
This patch must be backported as far as 2.2.
