drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc
[ Upstream commit 88a9a467c548d0b3c7761b4fd54a68e70f9c0944 ]
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)
