Eric Dumazet 7c03ab555e sched: act_ct: take care of padding in struct zones_ht_key 
[ Upstream commit 2191a54f63225b548fd8346be3611c3219a24738 ]

Blamed commit increased lookup key size from 2 bytes to 16 bytes,
because zones_ht_key got a struct net pointer.

Make sure rhashtable_lookup() is not using the padding bytes
which are not initialized.
