drm_atomic_private_obj_fini list corruption on driver init since 5.19 with RX 5700XT

On RX 5700 XT, ever since kernel 5.19, I'm getting kernel list corruption with CONFIG_BUG_ON_DATA_CORRUPTION=y on ppc64le.

Full backtrace:

I have not been able to narrow it down so far. It seems with CONFIG_BUG_ON_DATA_CORRUPTION disabled, the problem may not be encountered, but this still indicates a bug in the driver.

On 5.18 kernel and earlier, this problem does not happen.
