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)

That's close, but what I meant was to have something like this instead:
uint32_t dummy = 0xffffffff; *size = &dummy.
Because tmp is overwritten by user values while parsing the command stream.

uint32_t *size = &tmp;
