init/modpost: conditionally check section mismatch to __meminit*
This reverts commit eb8f689046b8 ("Use separate sections for __dev/
_cpu/__mem code/data").
Check section mismatch to __meminit* only when CONFIG_MEMORY_HOTPLUG=n.
With this change, the linker script and modpost become simpler, and we
can get rid of the __ref annotations from the memory hotplug code.
