msm: mdss: always vote for ab/ib before solid fill starts on MDP3 



For fill area less than half of screen size driver was not updating
ab/ib vote and assumed fudge in existing PPP vote should cover up
for solid fill bandwidth need.
Now vote for ab/ib before solid fill operation starts, irrespective of
the fill area size to prevent MDP under voting.
