HID: u2fzero: properly handle timeouts in usb_submit_urb
[ Upstream commit 43775e62c4b784f44a159e13ba80e6146a42d502 ]
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.
