IB/rds: Correct ib_api use with gs_dma_address/sg_dma_len
0b088e00 ("RDS: Use page_remainder_alloc() for recv bufs") added uses of sg_dma_len() and sg_dma_address(). This makes RDS DOA with the qib driver. IB ulps should use ib_sg_dma_len() and ib_sg_dma_address respectively since some HCAs overload ib_sg_dma* operations.
