To allocate larger buffer, MODS code is allocating noncontiguous pages and then calls dma buffer api to do smmu mapping to get a continuous iova address. This change will fix the error when the scatterlist's dma address is 0xffffffffffffffff, skip checking the sg since it's already merged to the head node.
