'Fix' ANR in holiday build happening frequently from lockscreen.

  Bug: 18854352

Note: This is more of a hack around the already pretty hacky camera
open-close lock. Proper fix is to refactor the code to not require this
lock anymore. But to get the holiday droidfood going further, this is
a quick for now.
