If ryu tries to parse segmented OF packets by the packet library, the process becomes infinite loop, bacause Ryu tries to parse OpenFlow header for the segmented packets, which don't have OpenFlow header, they only have body. This commit fixes this by stopping parsing OpenFlow header when the result is invalid.
