Support vlan insertion in vxlan header
Signed-off-by: Allen Chen <[email protected]>

After vxlan encapsulation,an underlay packet becomes vxlan packet.
OVS will report an debug info if a vlan is inserted in vxlan header after vxlan
encapsulation.
We can find the debug info "unsupported nested action inside clone(),action
type:4" by
"cat /var/log/openvswitch/ovs-vswitchd.log",so the ovs flow can not be
offloaded successfully.
For example,an underlay packet can be:Eth header/IP header/Payload,
after vxlan encapsulation,it can be:Outer Eth header/Outer IP header/Outer
UDP/Vxlan header/Inner Eth header/Inner IP header/Payload,
after vlan insertion,it can be:Outer Eth header/Vlan header/Outer IP
header/Outer UDP/Vxlan header/Inner Eth header/Inner IP header/Payload.(the
debug info occur at this point)
This commit can fix the problem in this case.
