HID: u2fzero: properly handle timeouts in usb_submit_urb
The wait_for_completion_timeout function returns 0 if timed out or a
positive value if completed. Hence, "less than zero" comparison always
misses timeouts and doesn't kill the URB as it should, leading to
re-sending it while it is active.
Fixes: 42337b9d4d95 ("HID: add driver for U2F Zero built-in LED and RNG")
