xfrm: always initialize offload path

xfrm: always initialize offload path

[ Upstream commit c0f21029f123d1b15f8eddc8e3976bf0c8781c43 ]

Offload path is used for GRO with SW IPsec, and not just for HW
offload. So initialize it anyway.

Fixes: 585b64f5a620 ("xfrm: delay initialization of offload path till its actually requested")
