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.
