USB: usbtest: use URB_ZERO_PACKET for BULK-OUT transfers
Executing
| testusb -a -c 1 -t 3 -v 421 -s 2048
does not complete on the gadget side.
g_zero enqueues a 4096 bytes long buffer. The host sends 2048bytes which
is a multiple of wMaxPacketSize (either 64 or 512 bytes). The host is
done with sending data but the gadget waits for more.
Since the protocol does not include transfer-length-field sending a
terminating zero packet seems the only way out.
