[PATCH 1/2 v2] drm/amdgpu: avoid resource leak on SR-IOV VF with AMDGIM_FEATURE_RAS_CPER enabled

Original amdgpu_cper_fini skips all CPER cleanup work for any SR-IOV VF directly. When AMDGIM_FEATURE_RAS_CPER is enabled on VF side, CPER related buffers/workitems are allocated during initialization, but the old code returns early without releasing these resources, which leads to kernel memory leak.
