Persist face error message for permanent lockout

Fixes the existing Keyguard and FaceService logic to correctly check for
and show a persistent error message when face authentication is in
permanent lockout mode due to too many failed attempts.

Test: atest com.android.keyguard
Test: On Pixel 4/4XL, fail face auth 6+ times on lock screen

Before: Error message shown after 5th attempt, but not future attempts

After: Error message shown after 5th and all subsequent attempts

Fixes: 140134198
