mm/sparse: correct init section annotations

Browse Source 
The !SPARSEMEM_EXTREME stub of sparse_index_init() has no annotation but
the SPARSEMEM_EXTREME variant is __meminit.  So mark the stub __meminit
too.

mminit_validate_memmodel_limits() is only called by memory_present(),
which is __init.  So mark it __init.

sparse_usagebuf and sparse_usagebuf_end are only used by
sparse_init_early_section(), sparse_usage_init() and sparse_usage_fini(),
which are all __init.  So mark them __initdata.
