Subject: [PATCH] drivers: usb: fastboot: Fix full-speed usb descriptor
The host will report such error message if the fastboot device work in
full-speed mode: "Duplicate descriptor for config 1 interface 0
altsetting 0, skipping"
Fastboot device ack both full and high speed interface descriptors when
work in full-speed mode, that's will cause this issue.
Fix it.
