veth: sctp: add NETIF_F_SCTP_CRC to device features
Commit b17c706987fa ("loopback: sctp: add NETIF_F_SCTP_CSUM to device
features") added NETIF_F_SCTP_CRC to device features for lo device to
improve the performance of sctp over lo.
This patch is to add NETIF_F_SCTP_CRC to device features for veth to
improve the performance of sctp over veth.
