ipv6: resend MLD report if a link-local address completes DAD
RFC3590/RFC3810 specifies we should resend MLD reports as soon as a valid link-local address is available. We now use the valid_ll_addr_cnt to check if it is necessary to resend a new report. Changes since Flavio Leitner's version: a) adapt for valid_ll_addr_cnt b) resend first reports directly in the path and just arm the timer for mc_qrv-1 resends.
