USB: yurex: fix control-URB timeout handling
commit 372c93131998c0622304bed118322d2a04489e63 upstream.
Make sure to always cancel the control URB in write() so that it can be
reused after a timeout or spurious CMD_ACK.
Currently any further write requests after a timeout would fail after
triggering a WARN() in usb_submit_urb() when attempting to submit the
already active URB.
Reported-by: syzbot+e87ebe0f7913f71f2ea5@syzkaller.appspotmail.com
Fixes: 6bc235a2e24a ("USB: add driver for Meywa-Denki & Kayac YUREX")
Cc: stable <stable@vger.kernel.org> # 2.6.37
