ila: call nf_unregister_net_hooks() sooner

commit 031ae72825cef43e4650140b800ad58bf7a6a466 upstream.

syzbot found an use-after-free Read in ila_nf_input [1]

Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().

It should be done in the reverse way, with a synchronize_rcu().

This is a good match for a pre_exit() method.
