From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
[ Upstream commit 917d80d376ffbaa9725fde9e3c0282f63643f278 ]
Use nf_msecs_to_jiffies64 and nf_jiffies64_to_msecs as provided by
8e1102d5a159 ("netfilter: nf_tables: support timeouts larger than 23
days"), otherwise ruleset listing breaks.
Fixes: a8b1e36d0d1d ("netfilter: nft_dynset: fix element timeout for HZ != 1000")
