[PM-22854] Fix biometric setup not resetting the setting in browser

[quexten]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-22854

📔 Objective

The setup did not return early correctly in two places, and did not set the setup result in case authentication was cancelled, making the biometrics setting stay active. This fixes the behavior by returning early and setting the setup result properly.
