odp-util: fill IPv4 ver and head length for tnl_push

Browse Source 
When parse tnl_push, if IPv4 is used,
    we forget to fill the ipv4 version and ip header length fields.

    so there is a wrong ip header in the header of "struct ovs_action_push_tnl",
    which will caused wrong packdet sent by dpcl.

    test command:
    ovs-appctl dpctl/add-flow "in_port(1),eth_type(0x0800),ipv4(dst=9.9.9.6)" \
    "tnl_push(tnl_port(2),header(size=50,type=4,eth(dst=08:00:27:2e:87:0d,src=98:03:9b:c6:d1:7c,dl_type=0x0800), \
    ipv4(src=10.97.240.147,dst=10.96.74.33,proto=17,tos=0,ttl=64,frag=0x4000), \
    udp(src=0,dst=4789,csum=0x0),vxlan(flags=0x8000000,vni=0x270f)),out_port(3)),4"
