USB: serial: io_edgeport: add missing active-port sanity check
commit 1568c58d11a7c851bd09341aeefd6a1c308ac40d upstream.
The driver receives the active port number from the device, but never
made sure that the port number was valid. This could lead to a
NULL-pointer dereference or memory corruption in case a device sends
data for an invalid port.
