[PATCH 5.2 005/124] netfilter: nf_flow_table: set default timeout after successful insertion

[Greg Kroah-Hartman]

From: Pablo Neira Ayuso <pa...@netfilter.org>

commit 110e48725db6262f260f10727d0fb2d3d25895e4 upstream.

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")
