USB: serial: digi_acceleport: stop OOB I/O when not in use
The driver submits the OOB read urb on first open of a port and does not
stop it until the device is disconnected.
Add an open counter and submit the urb on first open and stop it on last
close to avoid wasting resources (e.g. power) when the device is not in
use.
