Face auth bypass layout issues

The notification shade height isn't stable on swipe up. Unsure
what regressed this but add a check for bypass only that ensures
a stable height as the user is swiping up. This matches other
checks in the same file. Along with this, the AOD icons in bypass
mode would also adjust while swiping. The existing code already
accounts for bypass so remove the extra checks.
