QuotaMgmtClient returning negative usage values for resources that arent being utilized in subscription

- **Package Name**: azure-mgmt-quota
- **Package Version**: 1.1.0
- **Operating System**: Windows 11
- **Python Version**: 3.11.9

**Describe the bug**
The Azure Quota Management SDK (QuotaMgmtClient) returns -1 values for certain resources, the response values for resources that aren't used should be 0 and not -1. In the Azure Portal the same resources that show - 1 usage values show 0 usage values. 35 resource types under compute all return -1 usage values when not being utilized in subscription.

**To Reproduce**
Steps to reproduce the behavior:
1. Install library

```
pip install azure-mgmt-quota
```

2. Run code snippet using QuotaMgmtClient (Simplified code snippet)

```
from azure.identity import DefaultAzureCredential
from azure.mgmt.quota import QuotaMgmtClient
import logging

logger = logging.getLogger(__name__)

logging.basicConfig(
filename="compute_usages.log", encoding="utf-8", level=logging.DEBUG
)

def main():
client = QuotaMgmtClient(
credential=DefaultAzureCredential(),
)

response = client.usages.list(
scope="subscriptions/{subscription_id}/providers/Microsoft.Compute/locations/southafricanorth",
)

current_usages = []

for item in response:

payload = {"name": item.name, "usage": item.properties.usages.value,
"isQuotaApplicable" : item.properties.is_quota_applicable}
logging.info(payload)
current_usages.append(payload)

logging.info(current_usages)

if __name__ == "__main__":
main()

```

**Expected behavior**
Resources that have no usage should return a usage value of 0. This should align with what's displayed in the Azure portal under Quotas.

**Extract of output**
```
[
{'name': 'standardNDSFamily', 'usage': -1, 'isQuotaApplicable': False
},
{'name': 'standardNCSv2Family', 'usage': -1, 'isQuotaApplicable': False
},
{'name': 'standardNCSv3Family', 'usage': -1, 'isQuotaApplicable': False
},
]
```
