Switch over to using explicit old/new planes states instead of digging the old state out via plane->state. The main issue is that plane->state will point to the uapi state which we generally don't even want to look at. Also it sets a bad example as using plane->state during commit_tail() would be a bug. Here we're still holding the modeset locks so it's actually safe, but best not give people bad ideas.

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.
