David Hildenbrand 4eb29bd9d0 mm/page_alloc: drop stale pageblock comment in memmap_init_zone*() 
Commit ac5d2539b238 ("mm: meminit: reduce number of times pageblocks are
set during struct page init") moved the actual zone range check, leaving
only the alignment check for pageblocks.

Let's drop the stale comment and make the pageblock check easier to read.
