ipa: af_hill_climb: Skip the first frame after triggering auto focus
When AFTrigger is received, AF algorithm internal state is reset to initial values. If reset happens between frames, then first contrast value that arrives after this, is interpreted as contrast for initial position. This is wrong, because it was measured for lens position before the reset. Skip this first frame to allow correct contrast measure for the initial lens position.
