Fixes a bug that checkpoint_num_classes cannot be set through YAML file:

Use case: Downloaded pre-trained checkpoint from sghub locally and want to train a model with 1 class instead of 80. Since it's local checkpoint, not using pretrain_weights but checkpoint_path. In this case must specify checkpoint_num_classes but it is not propagated properly.

checkpoint_params:
 checkpoint_num_classes: 80
 num_classes: 1
 checkpoint_path: /yolo_nas_m_coco.pth
 strict_load: key_matching
