net: ipv4: Set addr_type in hash_keys for forwarded case

The result of the skb flow dissect is copied from keys to hash_keys to
ensure only the intended data is hashed. The original L4 hash patch
overlooked setting the addr_type for this case; add it.

Fixes: bf4e0a3d ("net: ipv4: add support for ECMP hash policy choice")
