greybus: Notify user space only when the test finished.

Browse Source 
Currently, user space is notified for every message sent,
but this is not really needed and does not work in the async case
where all messages are sent from the start.

Instead, notify userspace only when all the transfers are complete.
This allows userspace to wait in a poll loop and wakeup only when
the test is finished.

Also, don't use the bundle kobj to send the notification it is
the loopback device that contains the loopback attributes.
