Fix hang in TX when a libusb error occurs.

Browse Source 
Where our callback is called with a status other than COMPLETED,
something abnormal has happened and we no longer want to either
submit further transfers or await a flush. So clear the streaming
and flush flags, and proceed to transfer_finished.

Do the same in the case where libusb_submit_transfer fails when
called to submit the flush transfer.
