In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes svc_rdma_put_frmr() which in turn tries to unmap the same sg list through ib_dma_unmap_sg() again. This second unmap is invalid and could lead to problems when the iova being unmapped is subsequently reused. Remove the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr() handle it.
