[YueHaibing]

Fix build error:

net/rds/ib_cm.c: In function rds_dma_hdrs_alloc:
net/rds/ib_cm.c:475:13: error: implicit declaration of function dma_pool_zalloc; did you mean mempool_alloc? [-Werror=implicit-function-declaration]
   hdrs[i] = dma_pool_zalloc(pool, GFP_KERNEL, &hdr_daddrs[i]);
             ^~~~~~~~~~~~~~~
             mempool_alloc

net/rds/ib.c: In function rds_ib_dev_free:
net/rds/ib.c:111:3: error: implicit declaration of function dma_pool_destroy; did you mean mempool_destroy? [-Werror=implicit-function-declaration]
   dma_pool_destroy(rds_ibdev->rid_hdrs_pool);
   ^~~~~~~~~~~~~~~~
   mempool_destroy
