vcomp/cmpto_j2k: disable CUDA buffers with |GPU|>1

Browse Source 
Disable copying to CUDA buffers if there is more CUDA devices configured,
it does cause the following error:
```
[J2K enc.] Setting image samples: Cannot configure input samples in CUDA
buffer because argument 'device_id' doesn't match the configured CUDA
device in encoder. Single CUDA encoder must be configured.
```
