Johan Hovold 5182c2cf2a USB: serial: mos7840: fix another NULL-deref at open ...

Fix another NULL-pointer dereference at open should a malicious device
lack an interrupt-in endpoint.

Note that the driver has a broken check for an interrupt-in endpoint
which means that an interrupt URB has never even been submitted.
