ZhenGuo Yin e33997e18d drm/amdgpu: clear set_q_mode_offs when VM changed
[Why]
set_q_mode_offs don't get cleared after GPU reset, nexting SET_Q_MODE
packet to init shadow memory will be skiped, hence there has a page fault.

[How]
VM flush is needed after GPU reset, clear set_q_mode_offs when
emitting VM flush.

Fixes: 8bc75586ea ("drm/amdgpu: workaround to avoid SET_Q_MODE packets v2")

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.
