Subject: [PATCH] Allow retrying non-interactive authentication

An active password conversation should not prevent a completed fingerprint
conversation from being started again. PamAuthenticator::tryUnlock() already
ignores authenticators that are still running, so let subsequent start
requests reach each authenticator.

This is a minimal backport of the state-guard removal in upstream commit
a5ed9ca0. It allows a fingerprint attempt interrupted by suspend to restart
without cancelling the password conversation.
