ofproto-dpif-xlate: Fix segmentation fault caused by tun_table
Currently, the revalidator thread may hit segmentation fault when geneve
TLV map is updated. It is because we may store the old TLV map (struct
tun_table) in the frozen state for recirculation, and we may access the
already freed old tun_table in xlate_actions().
This patch update the logic of getting tun_table so that we will use
the latest tun_table instead of the frozen one.
