camera: Block out endlessly looping focus clause

capture_auto_focus_result isn't updated from any realtime focus
callback, so waiting for it to change in order to complete the
capture introduces delay, and in some cases an infinite loop.

Remove the focus state verification, at least until such a
callback can be put in place.
