memory hotremove: unset migrate type "ISOLATE" after removal
We should unset migrate type "ISOLATE" when we successfully removed memory. But current code has BUG and cannot works well. This patch also includes bugfix? to change get_pageblock_flags to get_pageblock_migratetype(). Thanks to Badari Pulavarty for finding this.
