This patch makes it so that we add udp_tunnel.h to vxlan.h and geneve.h header files. This is useful as I plan to move the generic handlers for the port offloads into the udp_tunnel header file and leave the vxlan and geneve headers to be a bit more protocol specific. I also went through and cleaned out a number of redundant includes that where in the .h and .c files for these drivers.
