The USB_Host_SendControlRequest() function no longer automatically selects the Control pipe (pipe 0), so that other control type pipes can be used with the function.

The USB Host management task now saves and restores the currently selected pipe before and after the task completes.

* <b>Host Mode</b>
* - The USB_Host_SendControlRequest() function no longer automatically selects the Control pipe (pipe 0) to allow it to be used on
* other control type pipes. Care should be taken to ensure that the Control pipe is always selected before the function is called
* in existing projects where the Control pipe is to be operated on.
* - The USB Host management task now saves and restores the currently selected pipe before and after the task runs. Projects no longer
* need to manage this manually when calling the USB management task.
