net: ipvlan: Fix ipvlan device tso disabled while NETIF_F_IP_CSUM is set

[ Upstream commit ceae266bf0ae6564ac16d086bf749a096fa90ded ]

There's some NICs, such as hinic, with NETIF_F_IP_CSUM and NETIF_F_TSO
on but NETIF_F_HW_CSUM off. And ipvlan device features will be
NETIF_F_TSO on with NETIF_F_IP_CSUM and NETIF_F_IP_CSUM both off as
IPVLAN_FEATURES only care about NETIF_F_HW_CSUM. So TSO will be
disabled in netdev_fix_features.
For example:
Features for enp129s0f0:
rx-checksumming: on
tx-checksumming: on
        tx-checksum-ipv4: on
        tx-checksum-ip-generic: off [fixed]
        tx-checksum-ipv6: on
