mm/zsmalloc.c: remove confusing code in obj_free()
Patch series "Cleanup for zsmalloc". This series contains cleanups to remove confusing code in obj_free(), combine two atomic ops and improve readability for async_free_zspage(). More details can be found in the respective changelogs. This patch (of 2): OBJ_ALLOCATED_TAG is only set for handle to indicate allocated object. It's irrelevant with obj. So remove this misleading code to improve readability.
