[PATCH][next] xfrm: fix missing break on AF_INET6 case

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

It appears that there is a missing break statement for the AF_INET6 case
that falls through to the default WARN_ONCE case. I don't think that is
intentional. Fix this by adding in the missing break.

Addresses-Coverity: ("Missing break in switch")
Fixes: 4c203b0454b5 ("xfrm: remove eth_proto value from xfrm_state_afinfo")
