MINOR: resolvers: Remove server from named_servers tree when removing a SRV item

When a server is cleaned up because the corresponding SRV item is removed,
we always remove the server from the srvrq's name_servers tree. For now, it
is useless because, if a server was attached to a SRV item, it means it was
already removed from the tree. But it will be mandatory to fix a bug.
