Issue: Memory Corruption in torch.lstm caused by edge cases
Labels: module: crash,module: rnn,triaged,module: edge cases

### 🐛 Describe the bug

A heap overflow might be triggered by the following code which calls `torch.lstm`:
````python
import torch
import numpy as np
input = torch.rand([15, 5, 0, 9], dtype=torch.float32).cuda()
hx_0 = torch.randint(-1024, 1024, [14, 4, 12, 7, 11], dtype=torch.int32).cuda()
hx_1 = torch.rand([8, 14, 15, 4, 0, 6], dtype=torch.float64).cuda()
hx = [hx_0, hx_1, ]
params = []
has_biases = False
num_layers = -49
dropout = 110.2580620604831
train = True
bidirectional = False
batch_first = True
res = torch.lstm(
    input=input,
    hx=hx,
    params=params,
    has_biases=has_biases,
    num_layers=num_layers,
    dropout=dropout,
    train=train,
    bidirectional=bidirectional,
    batch_first=batch_first,
)
````
The execution always ends up with **Segment Fault** or **Memory Corruption**:
````
corrupted size vs. prev_size
Aborted (core dumped)
# or
Segmentation fault (core dumped)
````
