fcoe: use CHECKSUM_UNNECESSARY instead of CHECKSUM_PARTIAL on tx
Fix a bug when using 'ethtool -K ethx tx off' to turn off tx ip checksum,
FCoE CRC offload should not be impacte. The skb_checksum_help() is needed
only if it's not FCoE traffic for ip checksum, regardless of ethtool toggling
the tx ip checksum on or off. Instead of using CHECKSUM_PARTIAL, we will
use CHECKSUM_UNNECESSARY as a proper indication to avoid sw ip checksum
on FCoE frames.
