When we flush usage, wait, indebt stat in iocg_flush_stat(), we use local_stat and desc_stat, which has no point since the leaf iocg only has local_stat and the inner iocg only has desc_stat. Also we don't need to flush percpu abs_vusage for these inner iocgs. This patch combine local_stat and desc_stat to stat, only flush percpu abs_vusage for active leaf iocgs, then build inner walk list to propagate.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
