is_pageblock_removable_nolock() relies on having zone association to examine all the page blocks to check whether they are movable or free. This is just wasting of cycles when the memblock is offline. Later patch in the series will also change the time when the page is associated with a zone so we let's bail out early if the memblock is offline.
