Philipp Stanner d506703472 Revert "drm/nouveau: Remove waitque for sched teardown" 
This reverts:

commit bead880022 ("drm/nouveau: Remove waitque for sched teardown")
commit 5f46f5c7af ("drm/nouveau: Add new callback for scheduler teardown")

from the drm/sched teardown leak fix series:

https://lore.kernel.org/dri-devel/20250710125412.128476-2-phasta@kernel.org/

The aforementioned series removed a blocking waitqueue from
nouveau_sched_fini(). It was mistakenly assumed that this waitqueue only
prevents jobs from leaking, which the series fixed.

The waitqueue, however, also guarantees that all VM_BIND related jobs
are finished in order, cleaning up mappings in the GPU's MMU. These jobs
must be executed sequentially. Without the waitqueue, this is no longer
guaranteed, because entity and scheduler teardown can race with each
other.

Revert all patches related to the waitqueue removal.

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 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.
