usb: usbtest: Always clear halt else further tests will fail
In test_halt() we set an endpoint halt condition and return on halt verification failure, then the enpoint will remain halted and all further tests related to that enpoint will fail. This is because we don't tackle endpoint halt error condition in any of the tests. To avoid that situation, make sure to clear the halt condition before exiting test_halt().
