Subject: [PATCH v5 02/16] mm/mm_init: rename init_reserved_page to init_deferred_page

From: "Mike Rapoport (Microsoft)" <rppt@...nel.org>

When CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, init_reserved_page()
function performs initialization of a struct page that would have been
deferred normally.

Rename it to init_deferred_page() to better reflect what the function does.
