mm: define __init_reserved_page_zone function

Browse source

Sometimes page structs must be unconditionally initialized as reserved,
regardless of DEFERRED_STRUCT_PAGE_INIT.

Define a function, __init_reserved_page_zone, containing code that already
did all of the work in init_reserved_page, and make it available for use.
