drm/amd/display: fix a regression in blank pixel data caused by coding mistake
[why] There was unfortunately a coding mistake. It gets caught with an ultrawide monitor that requires ODM 4:1 combine. We are blanking or unblanking pixel data we are supposed to enumerate through all ODM pipes and program DPG for each of those pipes. However the coding mistake causes us to program only the first and last ODM pipes.
