ipv4: Switch inet_addr_hash() to less predictable hash.
Recently, commit 4a0ec2aa0704 ("ipv6: switch inet6_addr_hash()
to less predictable hash") and commit 4daf4dc275f1 ("ipv6: switch
inet6_acaddr_hash() to less predictable hash") hardened IPv6
address hash functions.
inet_addr_hash() is also highly predictable, and a malicious use
could abuse a specific bucket.
Let's follow the change on IPv4 by using jhash_1word().
