[PATCH] Bluetooth: btmtk: fix urb->setup_packet leak in error paths

[Jiajia Liu]

The setup_packet of control urb is not freed if usb_submit_urb fails or
the submitted urb is killed. Add free in these two paths.

Fixes: a1c49c434e150 ("Bluetooth: btusb: Add protocol support for MediaTek MT7668U USB devices")
