[PATCH] drm/amdgpu_dm: tests: Fix wrong variable declaration after merge conflict

[Maxime Ripard <mripard@kernel.org>]

Commit 2bcec01cf105 ("drm/amdgpu_dm: Convert to atomic_create_state")
converted dm_test_plane_create_state_initializes_state() to call
amdgpu_dm_plane_drm_plane_create_state(), which returns a struct
drm_plane_state pointer stored in a new plane_state variable.

However, the merge conflict resolution kept the old declaration
(struct dm_plane_state *old_state) instead of replacing it with
struct drm_plane_state *plane_state, leaving an unused variable with
the wrong type.

Fix the declaration to match what the conversion intended.
