When purge lazily freed vmap areas, VA stored in vn->pool[] will also be taken away into free vmap tree partially or completely accordingly, that is done in decay_va_pool_node(). When doing that, for each pool of node, the whole list is detached from the pool for handling. At this time, that pool is empty. It's not necessary to update the pool size each time when one VA is removed and addded into free vmap tree. Here change code to update the pool size when attaching the pool back.

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 reStructuredText 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.
