USB: serial: digi_acceleport: fix port registration order

The driver submits the read urbs for all ports when the first port is
opened, which could happen before the other ports have been probed and
their private data set up.

If such an urb completes before the port has been probed, the completion
handler will not resubmit it, thus preventing any further reads.

Fix the ordering issue by not submitting the port read urbs until the
port is opened.

This also avoids wasting resources (e.g. power) when ports are not in
use.

Note that the port write urbs are already stopped on close (unless
unbinding, but they are also stopped by core on disconnect).
