Two leftovers from earlier fixes of the same shape. BraggIntegrationEngineGPU still read
device 0's shared-memory size to decide whether its profile grid fits; workers are pinned
round-robin across GPUs, so on a heterogeneous node that check can pass on a different
card than the one the kernel launches on. SpotExtractorGPU still uploaded its default
resolution mask with a pageable copy on the NULL stream, which is not ordered against the
engine stream now that streams are created non-blocking.
