Camera: Fix histogram on/off states

* It made the intended behavior reverted. Histogram mode was being
  set as enabled by default, but the histogram graph was not shown on
  screen. When disabling histogram feature, then the graph was being
  displayed. In other words, completely opposite of how it should work.

* Moving disable values before enable values seems to fix this.
