netfilter: flowtable: Set offload timeout when adding flow 



On heavily loaded systems the GC can take time to go over all existing
conns and reset their timeout. At that time other calls like from
nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as
expired. To fix this when we set the offload bit we should also reset
the timeout instead of counting on GC to finish first iteration over
all conns before the initial timeout.
