provider/azurerm: Reordering the checks after an Azure API Get
...
We are receiving suggestions of a panic as follows:
```
2016/09/01 07:21:55 [DEBUG] plugin: terraform: panic: runtime error: invalid memory address or nil pointer dereference

```
This is because the code is as follows:
```
resp, err := client.Get(resGroup, vnetName, name)
if resp.StatusCode == http.StatusNotFound {
d.SetId("")
return nil
}
if err != nil {
return fmt.Errorf("Error making Read request on Azure virtual network peering %s: %s", name, err)
}
```
When a request throws an error, the response object isn't valid. Therefore, we need to flip that code to check the error first
```
resp, err := client.Get(resGroup, vnetName, name)
if err != nil {
return fmt.Errorf("Error making Read request on Azure virtual network peering %s: %s", name, err)
}
if resp.StatusCode == http.StatusNotFound {
d.SetId("")
return nil
}
```
