There is a flow_stats structure defined in include/net/flow_offload.h
which is placed in the networking core. I think that definition takes
precedence on OVS, so rename flow_stats in OVS to sw_flow_stats.

OVS compilation breaks here after this patchset since flow_stats
structure is already defined in include/net/flow_offload.h. This patch
is new in this batch.
