Bluetooth: Handle bulk URBs in btusb driver from notify callback
With the addition of usb_unlink_anchored_urbs() it is possible to fully control the bulk URBs from the notify callback. There is no need to schedule work and so only do this for the ISOC URBs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
