USB: serial: fix potential NULL-dereference at probe
commit 126d26f66d9890a69158812a6caa248c05359daa upstream.
Make sure we have at least one port before attempting to register a
console.
Currently, at least one driver binds to a "dummy" interface and requests
zero ports for it. Should such an interface also lack endpoints, we get
a NULL-deref during probe.
