Bluetooth: Ignore isochronous endpoints for Intel USB bootloader

commit d92f2df0565ea04101d6ac04bdc10feeb1d93c94 upstream.

The isochronous endpoints are not valid when the Intel Bluetooth
controller boots up in bootloader mode. So just mark these endpoints
as broken and then they will not be configured.
