disp: msm: sde: clear cached rectangles when PU ROI is set

Browse Source 
clear cached rectangles when PU ROI is set to avoid incorrect
cached rois when two subsequent state duplications occur due
to timing. This will lead to commit N and commit N+1 to have
same cached ROIs as commit N-1. This results in issues when
commit N-1 is PU, N is full frame and N+1 is PU with same
ROI as N-1.
