netfilter: nf_tables: elements with timeout below CONFIG_HZ never expire
[ Upstream commit e0c47281723f301894c14e6f5cd5884fdfb813f9 ]
Element timeout that is below CONFIG_HZ never expires because the
timeout extension is not allocated given that nf_msecs_to_jiffies64()
returns 0. Set timeout to the minimum value to honor timeout.
Fixes: 8e1102d5a159 ("netfilter: nf_tables: support timeouts larger than 23 days")
