    Enforce driver is initialized

    This updates the volume manager and the
    backup manager to enforce that the driver
    has been initialized.

    The managers call the driver in many places
    without ensuring that the driver has been
    properly initialized. When the driver fails
    inside of do_setup(), the managers shouldn't
    call the driver's set_initialized() method.
    The managers now dump out the exception, and
    exit the init_host, leaving the driver in
    an uninitialized state.

    Fixes bug #1225897
