[XFRM]: Fix crash introduced by struct dst_entry reordering
XFRM expects xfrm_dst->u.next to be same pointer as dst->next, which
was broken by the dst_entry reordering in commit 1e19e02c~, causing
an oops in xfrm_bundle_ok when walking the bundle upwards.
Kill xfrm_dst->u.next and change the only user to use dst->next instead.
