mm: replace module_init usages with subsys_initcall in nommu.c
Compiling some arm/m68k configs with "# CONFIG_MMU is not set" reveals two more instances of module_init being used for code that can't possibly be modular, as CONFIG_MMU is either on or off. We replace them with subsys_initcall as per what was done in other mmu-enabled code. 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 subsys_initcall (which makes sense for these files) will thus change this registration from level 6-device to level 4-subsys (i.e. slightly earlier). One might think that core_initcall (l2) or postcore_initcall (l3) would be more appropriate for anything in mm/ but if we look at the actual init functions themselves, we see they are just sysctl setup stuff, and hence the choice of subsys_initcall (l4) seems reasonable. At the same time it minimizes the risk of changing the priority too drastically all at once. We can adjust further in the future. Also, a couple instances of missing ";" at EOL are fixed.
