Revert "xfrm: add SA information to the offloaded packet"

This reverts commit e7cd191f83fd899c233dfbe7dc6d96ef703dcbbd.

While supporting xfrm interfaces in the packet offload API
is needed, this patch does not do the right thing. There are
more things to do to really support xfrm interfaces, so revert
it for now.
