netfilter: flowtable: cache info of last offload
Modify flow table offload to cache the last ct info status that was passed to the driver offload callbacks by extending enum nf_flow_flags with new "NF_FLOW_HW_ESTABLISHED" flag. Set the flag if ctinfo was 'established' during last act_ct meta actions fill call. This infrastructure change is necessary to optimize promoting of UDP connections from 'new' to 'established' in following patches in this series.
