Pavel Skripkin 0e721b8f2e NFC: port100: fix use-after-free in port100_send_complete
[ Upstream commit f80cfe2f26 ]

Syzbot reported UAF in port100_send_complete(). The root case is in
missing usb_kill_urb() calls on error handling path of ->probe function.

port100_send_complete() accesses devm allocated memory which will be
freed on probe failure. We should kill this urbs before returning an
error from probe function to prevent reported use-after-free

Fail log:
