Tina Zhang 30b8a98a1a drm/i915/gvt: Fix orphan vgpu dmabuf_objs' lifetime 
commit b549c252b1292aea959cd9b83537fcb9384a6112 upstream.

Deleting dmabuf item's list head after releasing its container can lead
to KASAN-reported issue:

  BUG: KASAN: use-after-free in __list_del_entry_valid+0x15/0xf0
  Read of size 8 at addr ffff88818a4598a8 by task kworker/u8:3/13119

So fix this issue by puting deleting dmabuf_objs ahead of releasing its
container.

README 

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.
