net: usb: kalmia: validate USB endpoints

Browse source

commit c58b6c29a4 upstream.

The kalmia driver should validate that the device it is probing has the
proper number and types of USB endpoints it is expecting before it binds
to it.  If a malicious device were to not have the same urbs the driver
will crash later on when it blindly accesses these endpoints.
