From: YiPing Xu <xuyiping@xxxxxxxxxx>
Subject: zsmalloc: drop unused member 'mapping_area->huge'

When unmapping a huge class page in zs_unmap_object, the page will be
unmapped by kmap_atomic.  the "!area->huge" branch in __zs_unmap_object is
alway true, and no code set "area->huge" now, so we can drop it.
