Re: [PATCH v6 09/12] nvme-rdma: use ib_dma_map_sgtable_attrs()

ib_dma_map_sg() folds every mapping error into a zero return, losing
the DMA layer's error code.  Switch both scatterlist mappings to
ib_dma_map_sgtable_attrs(), which preserves it for the next patch to
act on.  No behavior change: failures are still reported as -EIO.

A local sg_table is needed: dma_map_sgtable() maps orig_nents
entries, and the embedded table's orig_nents is the allocated count,
not the count blk_rq_map_sg() produced.  rdma_rw_ctx_init() does the
same.
