dns: Set the result to null in cancelLookup()

Browse source 
When lookupHost() is called the handle returned
from allocateHandle() might be a reused handle.

The delegate will be cleared, but the result might
still be there and the assert in lookupHost()
will fail:

```
assert(!m_lookups[handle].result);
```
