Michal Hocko 8b0662f245 mm, memory_hotplug: consider offline memblocks removable 
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.
