[net-next,0/6] xfrm: Convert __xfrm4_dst_lookup() and its callers to dscp_t.

This patch series continues to prepare users of ->flowi4_tos to a
future conversion of this field (__u8 to dscp_t). This time, we convert
__xfrm4_dst_lookup() and its call chain.

The objective is to eventually make all users of ->flowi4_tos use a
dscp_t value. Making ->flowi4_tos a dscp_t field will help avoiding
regressions where ECN bits are erroneously interpreted as DSCP bits.

Note: I'm sending this series to net-next as these are generic
networking changes, although they only touch xfrm files. But I'm happy
to rebase over ipsec-next if that's prefered. Just let me know.
