USB: cdc-acm: handle broken union descriptors
[ Upstream commit 960c7339de27c6d6fec13b54880501c3576bb08d ]
Handle broken union functional descriptors where the master-interface
doesn't exist or where its class is of neither Communication or Data
type (as required by the specification) by falling back to
"combined-interface" probing.
Note that this still allows for handling union descriptors with switched
interfaces.
This specifically makes the Whistler radio scanners TRX series devices
work with the driver without adding further quirks to the device-id
table.
