ipvs: Fix checksumming on GSO of SCTP packets

[ Upstream commit e10d3ba4d434ed172914617ed8d74bd411421193 ]

It was observed in the wild that pairs of consecutive packets would leave
the IPVS with the same wrong checksum, and the issue only went away when
disabling GSO.

IPVS needs to avoid computing the SCTP checksum when using GSO.
