Do not reset keyguard state from delay while dreaming.

This changelist makes sure that the delayed keyguard lock after dreaming
does not lead to the keyguard reseting its state. Doing so will cause
the notification shade to collapse. This can lead to the UI disappearing
and dismiss logic dependent on shade collapse not working properly.
