drm/amd/display: Fix p-state type when p-state is unsupported

Browse Source 
[ Upstream commit a025f424af0407b7561bd5e6217295dde3abbc2e ]

[WHY&HOW]
P-state type would remain on previously used when unsupported which
causes confusion in logging and visual confirm, so set back to zero
when unsupported.
