dpif-netlink: Generate ufids for installing TC flowers

Browse Source 
To support installing the TC flowers to HW, via "ovs-appctl dpctl/add-flow"
command, there should be an ufid. This patch will check whether ufid exists,
if not, generate an ufid. Should to know that when processing upcall packets,
ufid is generated in parse_odp_packet for kernel datapath.

Configuring the max-idle/max-revalidator, may help testing this patch.
