drm/amdgpu/powerplay/psm: Fix memory leak in power state init 

[ Upstream commit 8f8033d566 ]

Commit 902bc65de0 ("drm/amdgpu/powerplay/psm: return an error in power
state init") made the power state init function return early in case of
failure to get an entry from the powerplay table, but it missed to clean up
the allocated memory for the current power state before returning.
