xfrm: provide common xdo_dev_offload_ok callback implementation
Almost all drivers except bond and nsim had same check if device
can perform XFRM offload on that specific packet. The check was that
packet doesn't have IPv4 options and IPv6 extensions.
In NIC drivers, the IPv4 HELEN comparison was slightly different, but
the intent was to check for the same conditions. So let's chose more
strict variant as a common base.
