xfrm: restore GSO for SW crypto
Commit 49431af6c4ef incorrectly assumes that the GSO path is only used
by HW offload, but it's also useful for SW crypto.
This patch re-enables GSO for SW crypto. It's not an exact revert to
preserve the other changes made to xfrm_dev_offload_ok afterwards, but
it reverts all of its effects.
Fixes: 49431af6c4ef ("xfrm: rely on XFRM offload")
