openvswitch: Move mega-flow list out of rehashing struct.
ovs-flow rehash does not touch mega flow list. Following patch moves it dp struct datapath. Avoid one extra indirection for accessing mega-flow list head on every packet receive. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com>
