drm/amd/display: Cover crtc destroy_state stream release

Browse source

Add dm_test_crtc_destroy_state_releases_stream to cover the cur->stream
branch of amdgpu_dm_crtc_destroy_state(), complementing the existing
no-stream test.

The test attaches a DC stream to the CRTC state and takes an extra stream
reference so the destroy path drops back to the KUnit-managed reference
instead of freeing the stream, then verifies exactly one reference was
released.
