USB: cdc-wdm: Avoid hanging on interface with no USB_CDC_DMM_TYPE
commit 15699e6fafc3a90e5fdc2ef30555a04dee62286f upstream.
The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces. A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files. But this would fail with a 0 buffer length
due to the missing descriptor.
Fix by defining a reasonable fallback size: The minimum
device receive buffer size required by the CDC WMC standard,
revision 1.1
