Redundant condition and assignment in java.net.URI

1. Assignment `ru.host = child.host;` is duplicated and hence redundant in
java.net.URI#resolve(java.net.URI, java.net.URI)

2. Condition `q > p` is always `true`, because it just bellow inverse check
```
                if (q <= p)
                    break;
```
