usb: core: add USB_QUIRK_NO_BOS for devices that hang on BOS descriptor

commit 2740ac33c87b3d0dfa022efd6ba04c6261b1abbd upstream.

Add USB_QUIRK_NO_BOS quirk flag to skip requesting the BOS descriptor
for devices that cannot handle it.

Add Elgato 4K X (0fd9:009b) to the quirk table. This device hangs when
the BOS descriptor is requested at SuperSpeed Plus (10Gbps).
