Florian Westphal e4650e3af0 netfilter: arp_tables: init netns pointer in xt_tgdtor_param struct 
commit 212e7f5660 upstream.

An earlier commit (1b789577f6,
"netfilter: arp_tables: init netns pointer in xt_tgchk_param struct")
fixed missing net initialization for arptables, but turns out it was
incomplete.  We can get a very similar struct net NULL deref during
error unwinding:

general protection fault: 0000 [#1] PREEMPT SMP KASAN
RIP: 0010:xt_rateest_put+0xa1/0x440 net/netfilter/xt_RATEEST.c:77

 do_arpt_set_ctl+0x317/0x650 net/ipv4/netfilter/arp_tables.c:1461

Also init the netns pointer in xt_tgdtor_param struct.

Fixes: add6746124 ("netfilter: add struct net * to target parameters")
