    Fixes for device image alarm

    This commit clears the in-progress alarm if there is no more
    pending, failed or in-progress device images to be updated
    after a device image is removed.

    It also raises the alarm only when there are pending image updates.
    If the system does not have any FPGA devices then the alarm is not
    raised as there is no image update to be processed.

    This commit also improved some comments about the applied field.
