netfilter: nf_tables: free flowtable hooks on hook register error
If hook registration fails, the hooks allocated via nft_netdev_hook_alloc
need to be freed.
We can't change the goto label to 'goto 5' -- while it does fix the memleak
it does cause a warning splat from the netfilter core (the hooks were not
registered).
Fixes: 3f0465a9ef02 ("netfilter: nf_tables: dynamically allocate hooks per net_device in flowtables")
