datapath: more accurate checksumming in queue_userspace_packet()

openvswitch: more accurate checksumming in queue_userspace_packet()
if skb carries an SCTP packet and ip_summed is CHECKSUM_PARTIAL, it needs
CRC32c in place of Internet Checksum: use skb_csum_hwoffload_help to avoid
corrupting such packets while queueing them towards userspace.
