Johan Hovold bdd1b147b8 USB: quirks: blacklist duplicate ep on Sound Devices USBPre2 
This device has a broken vendor-specific altsetting for interface 1,
where endpoint 0x85 is declared as an isochronous endpoint despite being
used by interface 2 for audio capture.

Since commit 3e4f8e21c4 ("USB: core: fix check for duplicate
endpoints") USB core ignores any duplicate endpoints found during
descriptor parsing, but in this case we need to ignore the first
instance in order to avoid breaking the audio capture interface.
