[PATCH] drm/amd/pm: skip to set mp1 unload state in special case

[Yang Wang]

set mp1 unload state will cause the SMC FW can't accept any SMU message,
skip to set mp1 unload state to avoid following case fail:
- runtime pm case.
- gpu reset case.

Fixes: 826126d8f805 ("drm/amd/pm: fix driver reload SMC firmware fail issue for smu13")
