dpif: Fix memory leak
Valgrind complains in test 2322 (ovn -- 3 HVs, 3 LS, 3 lports/LS, 1 LR): 31,584 (26,496 direct, 5,088 indirect) bytes in 48 blocks are definitely lost in loss record 422 of 427 by 0x5165F4: xmalloc (util.c:120) by 0x466194: dp_packet_new (dp-packet.c:138) by 0x466194: dp_packet_new_with_headroom (dp-packet.c:148) by 0x46621B: dp_packet_clone_data_with_headroom (dp-packet.c:210) by 0x46621B: dp_packet_clone_with_headroom (dp-packet.c:170) by 0x49DD46: dp_packet_batch_clone (dp-packet.h:789) by 0x49DD46: odp_execute_clone (odp-execute.c:616) by 0x49DD46: odp_execute_actions (odp-execute.c:795) by 0x471663: dpif_execute_with_help (dpif.c:1296) by 0x473795: dpif_operate (dpif.c:1411) by 0x473E20: dpif_execute.part.21 (dpif.c:1320) by 0x428D38: packet_execute (ofproto-dpif.c:4682) by 0x41EB51: ofproto_packet_out_finish (ofproto.c:3540) by 0x41EB51: handle_packet_out (ofproto.c:3581) by 0x4233DA: handle_openflow__ (ofproto.c:8044) by 0x4233DA: handle_openflow (ofproto.c:8219) by 0x4514AA: ofconn_run (connmgr.c:1437) by 0x4514AA: connmgr_run (connmgr.c:363) by 0x41C8B5: ofproto_run (ofproto.c:1813) by 0x40B103: bridge_run__ (bridge.c:2919) by 0x4103B3: bridge_run (bridge.c:2977) by 0x406F14: main (ovs-vswitchd.c:119) the parameter dp_packet_batch is leaked when 'may_steal' is true. When dpif_execute_helper_cb is passed with a true 'may_steal', it is supposed to take the ownership of dp_packet_batch and release it when done.
