This fixes the following race in reconfiguring link: 1. an interface requests UUID. 2. the interface is reconfigured and link_configure() is called. 3. sd-lldp client is started on the interface (it is enabled by default). 4. networkd acquires UUID, and get_product_uuid_handler() calls link_configure() for the link again. 5. link_lldp_rx_configure() fails to set ifindex for already running sd-lldp client. 6. the link enters failed state.
