    SRIOV: don't block report_state with device count

    The device count process can be quite slow on a system with
    lots of interfaces. Doing this during report_state can block
    it long enough that the agent will be reported as dead and
    bindings will fail.

    This adjusts the logic to only update the configuration during
    the normal device retrieval for the scan loop. This will leave
    the report_state loop unblocked by the operation so the agent
    doesn't get reported as dead (which blocks port binding).
