This also fixes the original issue introduced in this CL.
KeyguardAbsKeyInputViewController#reset would call mView#resetState
instead of its own internal resetState method. However, all the logic
from the various resetState methods had been moved from the views to
their controllers. Simply calling resetState direclty resolves the
issue (line 105 of KeyguardAbsKeyInputViewController).
