### Please describe the problem.
Context: As part of trying to get a non-star topology as described [here](https://git-annex.branchable.com/todo/Allow_remote_sync__42___and_ignore__42___in_git_annex_config/), I added remotes that are not online and don't have the ignore flag set.
Running `git annex info` (without additional args) causes git-annex to try to ssh to the enabled git special remote and then git fetch it which takes *minutes* to time out.
### What steps will reproduce the problem?
1. Add a reachable but unavailable ip address such as 101.101.101.101 to a local interface for setup
2. `git annex initremote bad type=git location=ssh://101.101.101.101:/tmp/foo`
3. Remove the address from the local interface again (and clear annex ssh caches)
4. `git annex info` (hangs)
