inconsistent output types for `correct_crop_centers`

[wyli]

Describe the bug

import torch
from monai.transforms.utils import correct_crop_centers

correct_crop_centers(
    centers=[torch.tensor(1), torch.tensor(5), torch.tensor(0)], 
    spatial_shape=[2, 2, 2], 
    label_spatial_shape=[10, 10, 10])
# [tensor(1), tensor(5), 1]

the data types of the output of correct_crop_centers shouldn't depend on data.
