Inconsistent behavior for in-place operations on coalesced sparse tensors
Labels: module: sparse, triaged

### 🐛 Describe the bug

When working with coalesced sparse COO tensors, calling `.div_` keeps the tensor coalesced, but `.mul_` does not. However, calling `.mul` returns a coalesced tensor.

```python
>>> i = torch.tensor([[0, 1, 1], [2, 0, 2]])
>>> v = torch.tensor([3, 4, 5], dtype=torch.float32)
>>> t = torch.sparse_coo_tensor(i, v, [2, 4]).coalesce()
>>> t.mul(2).is_coalesced()
True
>>> t.div(2).is_coalesced()
True
>>> t.div_(2).is_coalesced()
True
>>> t.mul_(2).is_coalesced()
False
```
