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.
