vxlan: Refactor vxlan_udp_encap_recv() to kill compiler warning 

drivers/net/vxlan.c: In function ‘vxlan_udp_encap_recv’:
drivers/net/vxlan.c:1226: warning: ‘info’ may be used uninitialized in this function

While this warning is a false positive, it can be killed easily by
getting rid of the pointer intermediary and referring directly to the
ip_tunnel_info structure.
