RDMA/rtrs-srv: Pass the correct number of entries for dma mapped SGL
ib_dma_map_sg() augments the SGL into a 'dma mapped SGL'. This process
may change the number of entries and the lengths of each entry.
Code that touches dma_address is iterating over the 'dma mapped SGL'
and must use dma_nents which returned from ib_dma_map_sg().
We should use the return count from ib_dma_map_sg for futher usage.
