[PATCH AUTOSEL 5.13 47/88] HID: thrustmaster: Fix memory leaks in probe

[Sasha Levin]

From: Evgeny Novikov <novikov at ispras.ru>

[ Upstream commit d0f1d5ae23803bd82647a337fa508fa8615defc5 ]

When thrustmaster_probe() handles errors of usb_submit_urb() it does not
free allocated resources and fails. The patch fixes that.

Found by Linux Driver Verification project (linuxtesting.org).
