Subject: USB: serial: visor: fix crash on detecting device without write_urbs

From: Vladis Dronov <[email protected]>

commit cb3232138e37129e88240a98a1d2aba2187ff57c upstream.

The visor driver crashes in clie_5_attach() when a specially crafted USB device without bulk-out endpoint is detected. This fix adds a check that the device has proper configuration expected by the driver.
