nvme-tcp: fix data digest pointer calculation
ddgst is of type __le32, &req->ddgst + req->offset increases &req->ddgst by 4 * req->offset, fix this by type casting &req->ddgst to u8 *. Fixes: 3f2304f8c6d6 ("nvme-tcp: add NVMe over TCP host driver") Signed-off-by: Varun Prakash <varun@chelsio.com> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Christoph Hellwig <hch@lst.de>
