This commit results in memory corruption on suspend/resume with short
suspend duration. Laptop appears to hang and crash is logged to pstore.

To reproduce: `amd_s2idle.py --log log --duration 1 --wait 4 --count 30`

I have reproduced this both with and without Mario's recent suspend fix
https://lore.kernel.org/amd-gfx/20250602014432.3538345-1-superm1@kernel.org/T/#t

Pstore log (with Mario's fix):
