dma-direct: Improve readability of the dma_direct_map_sg() for P2PDMA case

Browse Source 
Improve readability of the sg_dma_len assignment in the P2PDMA cases by
removing duplicated code, which was a direct result of the d0d08f4bd7
("dma-direct: Fix missing sg_dma_len assignment in P2PDMA bus mappings")
fix. No functional change.
