    drm/tests/gpu_buddy: fix interleaving in buffer clearance test
    
    The resume clearance test skipped every other allocation, expecting an
    interleaved clear/dirty layout. But the buddy allocator hands out blocks
    contiguously, so this just allocated half the pages in one chunk and never
    exercised gpu_buddy_reset_clear()'s force-merge of opposite-state buddies.
    Allocate all pages into two lists instead and free one cleared, one dirty,
    to build a truly interleaved pattern.
    
    v2: Use for loops instead of do-while for the allocation loops (Jani Nikula)
