Fix device of the tensors in set_nms

[max-unfinity]

Motivation

Fixed RuntimeError: indices should be either on cpu or on the same device as the indexed tensor (cpu) when running CrowdDet model on cuda device (the model uses MultiInstanceBBoxHead roi_head)

Modification

Just added tensor.to(device) to fix the issue in set_nms method.

        keep = keep.to(bboxes.device)
        ruler = ruler.to(bboxes.device)

versions:

• torch==2.0.1
• mmdet==3.0.0
• mmengine==0.7.4
