geneve: fix build with modular IPV6

Commit c40e89f ("geneve: configure MTU based on a lower device") added an IS_ENABLED(CONFIG_IPV6) to geneve, leading to the following link error with CONFIG_GENEVE=y and CONFIG_IPV6=m: drivers/net/geneve.o: In function `geneve_link_config': geneve.c:(.text+0x14c): undefined reference to `rt6_lookup' Fix this by adding a Kconfig dependency and forcing GENEVE to be a module when IPV6 is a module.
