drm/amd/display: Fix use-after-free bugs in KUnit tests

When running the KUnit tests with memory debugging enabled, a bunch of
use-after-free errors are hit. These are due to using KUnit managed
memory for the test objects but then giving them over to DRM managed
objects. The KUnit stuff is deallocated first and when the DRM side
calls its clean up helpers, it hits memory that has been freed already.

NB: There is still a use-after-free bug in the writeback tests.
However, fixing that requires driver side changes as well as test side
changes. Those changes are part of:
