Fix fingerprint error messages on Keyguard / AOD

1) "Too many attempts" message should be shown when AOD -> Keyguard
2) onFingerprintError() errors should not be cleared by previous
   onFingerprintHelp() messages (MSG_CLEAR_FP_MSG), otherwise the error
   won't be displayed for the full 5000ms
3) "Too many attempts" message should be shown when user is locked out
   on AOD
4) FINGERPRINT_ERROR_LOCKOUT_PERMANENT error should show whenever
   AOD or keyguard is entered (same as regular lockout message behavior)
