netif: ensure link and admin states are up in issue reports (bug #52353)

Browse Source 
This fixes a bug where some callers of netif_issue_reports were not
checking that both link and admin states were up, leading to extraneous
reports when calling one of the following

 1) netif_set_ipaddr
 2) netif_ip6_addr_set_parts
 3) netif_ip6_addr_set_state

The bug has been fixed by placing link and admin state checks in
netif_issue_reports and not requiring the callers to perform this
checking
