libpayload: Detach unresponsive usb mass storage devices

This enables logical detachment of unresponsive usb devices (i.e.
    devices not responding to control transfers) in the usb mass storage
    driver. Without the detection of unresponsive devices we wait way too
    long for the device to become ready.
