We were relying on the pinned screen object backup buffer to be destroyed when not used. But if we hold a copy of the atomic state, like when hibernating, the backup buffer might not be destroyed since it's refcounted by the atomic state. This causes us to hibernate with a buffer pinned in VRAM. Fix this by only having the buffer pinned when it is actually used by a screen object.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
