usb: fix the ID for the dual-band Wistron AR5523 USB NIC

Use the correct ID, as I have one of these NICs.
Add the previous one back in case it's out there in the wild.

@emaste did a bit of a dig into the product numbers.
@sam did change the ID from 0x0828 -> 082a in a commit
a long while back. It's worth reading the code review for
further details.

However, I do have one of these NICs and I verified that
it indeed has the given ID, and with some follow-up work
to fix some race conditions, it works fine in 2GHz 11bg
and 5GHz 11a operation.
