Incorrect device index in `StorageView`

[sumitupadhye12]

import torch
import ctranslate2

x0 = torch.ones((2, 4), dtype=torch.int32, device="cuda:0")
y0 = ctranslate2.StorageView.from_array(x0)

print(f"Original tensor is on {x0.device} and StorageView is on {y0.device}:{y0.device_index}")

x1 = torch.ones((2, 4), dtype=torch.int32, device="cuda:1")
y1 = ctranslate2.StorageView.from_array(x1)

print(f"Original tensor is on {x1.device} and StorageView is on {y1.device}:{y1.device_index}")

The output I get is

Original tensor is on cuda:0 and StorageView is on cuda:0
Original tensor is on cuda:1 and StorageView is on cuda:0

The actual data is still on cuda:0 for y0 and on cuda:1 for y1.
