Revert of Client side display item cache flag

Revert of Client side display item cache flag (patchset #20 id:380001 of https://codereview.chromium.org/1508223005/ )

Reason for revert:
This caused crbug.com/609218. It seems that there is some short-lived
DisplayItemClient but needs more investigations to find which
DisplayItemClient it is.

Revert this to unblock m-52 branch and beta release.

Will reland on m-53 and add some code in release builds to find the
reason.
