Florian Westphal 43016d02cf netfilter: arptables: use pernet ops struct during unregister
Like with iptables and ebtables, hook unregistration has to use the
pernet ops struct, not the template.

This triggered following splat:
  hook not found, pf 3 num 0
  WARNING: CPU: 0 PID: 224 at net/netfilter/core.c:480 __nf_unregister_net_hook+0x1eb/0x610 net/netfilter/core.c:480
