[NETFILTER]: Fix bridge netfilter related in xfrm_lookup
The bridge-netfilter code attaches a fake dst_entry with dst->ops == NULL to purely bridged packets. When these packets are SNATed and a policy lookup is done, xfrm_lookup crashes because it tries to dereference dst->ops. Change xfrm_lookup not to dereference dst->ops before checking for the DST_NOXFRM flag and set this flag in the fake dst_entry.
