netfilter: nft_dynset: fix element timeout for HZ != 1000
With HZ=100 element timeout in dynamic sets (i.e. flow tables) is 10 times
higher than configured.
Add proper conversion to/from jiffies, when interacting with userspace.
I tested this on Linux 4.8.1, and it applies cleanly to current nf and
nf-next trees.
Fixes: 22fe54d5fefc ("netfilter: nf_tables: add support for dynamic set updates")
