netfilter: flowtable: add nf_flowtable_time_stamp
This patch adds nf_flowtable_time_stamp and updates the existing code to
use it.
This patch is also implicitly fixing up hardware statistic fetching via
nf_flow_offload_stats() where casting to u32 is missing. Use
nf_flow_timeout_delta() to fix this.
Fixes: c29f74e0df7a ("netfilter: nf_flow_table: hardware offload support")
