net: openvswitch: rename flow_stats to sw_flow_stats
There is a flow_stats structure defined in include/net/flow_offload.h and a follow up patch adds #include <net/flow_offload.h> to net/sch_generic.h. This breaks compilation since OVS codebase includes net/sock.h which pulls in linux/filter.h which includes net/sch_generic.h. In file included from ./include/net/sch_generic.h:18:0, from ./include/linux/filter.h:25, from ./include/net/sock.h:59, from ./include/linux/tcp.h:19, from net/openvswitch/datapath.c:24 This definition takes precedence on OVS since it is placed in the networking core, so rename flow_stats in OVS to sw_flow_stats since this structure is contained in sw_flow.
