Description:
Calling MySqlCommand.Cancel on a new MySqlCommand object throws a NullReferenceException.

How to repeat:
Run the following C# code:

	using (var cmd = new MySqlCommand())
		cmd.Cancel();

Suggested fix:
If there isn't an active command, the call to Cancel should be a no-op (and succeed without throwing an exception).
