init,mm: fold late call to page_ext_init() to page_alloc_init_late()
When deferred initialization of struct pages is enabled, page_ext_init()
must be called after all the deferred initialization is done, but there is
no point to keep it a separate call from kernel_init_freeable() right
after page_alloc_init_late().
Fold the call to page_ext_init() into page_alloc_init_late() and localize
deferred_struct_pages variable.
