[ Upstream commit 053c8fdf2c930efdff5496960842bbb5c34ad43a ]

The xfrm{4,6}_beet_gso_segment() functions did not correctly set the
SKB_GSO_IPXIP4 and SKB_GSO_IPXIP6 gso types for the address family
tunneling case. Fix this by setting these gso types.

Fixes: 384a46ea7bdc7 ("esp4: add gso_segment for esp4 beet mode")
Fixes: 7f9e40eb18a99 ("esp6: add gso_segment for esp6 beet mode")
