[PATCH net 1/1] netfilter: conntrack: Check offload bit on table dump

Currently, offloaded flows might be deleted when executing conntrack -L
or cat /proc/net/nf_conntrack while rules being offloaded.
Ct timeout is not maintained for offloaded flows as aging
of offloaded flows are managed by the flow table offload infrastructure.

Don't do garbage collection for offloaded flows when dumping the
entries.
