Title: #744: ssh: sssd_ssh fails completely on p11_child timeout
Or was the idea behind the path that since the output is just a public key, we can go
But shouldn't the code fall through in that case instead of ending with success?
IMO we should ignore any error from p11_child. Just log it and continue. The idea comes
from normal ssh behaviour - if there is any error in one authentication method, ssh
continues with next one.
