IB/core: Remove ib_sg_dma_address() and ib_sg_dma_len()
Keeping single line wrapper functions is not useful. Hence remove the ib_sg_dma_address() and ib_sg_dma_len() functions. This patch does not change any functionality. Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
