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: bf4e0a3db97eb ("net: ipv4: add support for ECMP hash policy choice")
