For work challenges, do not reset incorrect password attempts if challenge is resolved via biometric authentication. This is the behaviour for personal keyguard and work challenge should be consistent. Bug: 139438785 Test: manual: enroll work challenge with fingerprint, set failed wipe count (3) via TestDPC and attempt two failed attempts (via cmd lock_settings). Resolve work challenge with fingerprint and attempt one last failed attempt. Verify work profiel is wiped. Change-Id: Ic64d3e44f3faa5adf8ac43db09e33c8403427990
