Subject: block: wbt: Remove unnecessary invoking of wbt_update_limits in wbt_init
From: Lei Chen <lennychen@xxxxxxxxxxx>
commit 5a20d073ec54a72d9a732fa44bfe14954eb6332f upstream.
It's unnecessary to call wbt_update_limits explicitly within wbt_init,
because it will be called in the following function wbt_queue_depth_changed.
