RDMA/rtrs-srv: Pass the correct number of entries for dma mapped SGL

Browse source

[ Upstream commit 56c310de0b ]

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.
