drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc

Browse Source 
commit 88a9a467c5 upstream.

Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001.
V2: To really improve the handling we would actually
   need to have a separate value of 0xffffffff.(Christian)
