[PATCH net-next] pktgen: do not abuse IN6_ADDR_HSIZE

[Eric Dumazet]

From: Eric Dumazet <eduma...@google.com>

pktgen accidentally used IN6_ADDR_HSIZE, instead of using the size of an
IPv6 address.

Since IN6_ADDR_HSIZE recently was increased from 16 to 256, this old
bug is hitting us.

Fixes: 3f27fb23219e ("ipv6: addrconf: add per netns perturbation in 
inet6_addr_hash()")
