Subject: [PATCH 5/5] netfilter: nf_flow_table: set default timeout after successful insertion

Set up the default timeout for this new entry otherwise the garbage
collector might quickly remove it right after the flowtable insertion.

Fixes: ac2a66665e23 ("netfilter: add generic flow table infrastructure")
