datapath: Use correct reply values in datapath and vport ops

This patch fixes the bug that all datapath and vport ops are returning
wrong values (OVS_FLOW_CMD_NEW or OVS_DP_CMD_NEW) in their replies.

This commit backports upstream net-next's commit 804fe108fc92e59
("openvswitch: Use correct reply values in datapath and vport ops").
