Fix use of auth-bound keys after screen lock removal

When an auth-bound key is used after the screen lock has been removed by
the user, KeyStore.begin retruns UNINITIALIZED.

This patch adds handling for this error code, indicating that the key
that was to be used was permanently invalidated.

Bug: 65200397
Test: CtsVerifier ScreenLockBoundKeysTest:
      1. Run test
      2. with CtsVerifier in the background remove the screen lock
         through the settings dialog
      3. Select VtsVerifier in 'recents'
      4. Run test again
