net/ipv4: don't use module_init in non-modular gre_offload
Recent commit 438e38fadca2f6e57eeecc08326c8a95758594d4 ("gre_offload: statically build GRE offloading support") added new module_init/module_exit calls to the gre_offload.c file. The file is obj-y and can't be anything other than built-in. Currently it can never be built modular, so using module_init as an alias for __initcall can be somewhat misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. We also make the inclusion explicit. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering. As for the module_exit, rather than replace it with __exitcall, we simply remove it, since it appears only UML does anything with those, and even for UML, there is no relevant cleanup to be done here.
