ipa: rpi: Fix frame count logic when running algorithms

Browse source 
The frame counter test to determine if we run the IPA algorithms has a
logic bug where it treats dropFrameCount_ and mistrustCount_ as frame
numbers, not counts of frames (which it is). The implication is that
startup convergence and initial settings take one extra frame to apply.
Fix this.
