When a ppa_list with vblks is expanded, it can either go block or plane first. Currently it is been plane first. This works well for a single vblk that is expanded, but fails for controllers that require data for all planes is grouped together. Make the ppa_list expand first expand with block, and then plane to support this behavior.
