[media] usbvision: fix crash on detecting device with invalid configuration

Orabug: stable_rc4

[ Upstream commit fa52bd506f274b7619955917abfde355e3d19ffe ]

The usbvision driver crashes when a specially crafted usb device with invalid
number of interfaces or endpoints is detected. This fix adds checks that the
device has proper configuration expected by the driver.
