sd-dhcp6-client: Properly handle DHCPv6 client restart after resume
Whenever a Router Advertisement is received, dhcp6_configure() will be called. A Router Advertisment can also instruct DHCPv6 to start acquiring IPv6 addresses in manged mode, if it previously was handling only other information. As an Router Advertisment is also received after the DHCPv6 client has resumed from a suspend, fix the function not to assume DHCPv6 is currently running, but instead try to restart it. Handle sd_dhcp6_start() returning -EALREADY indicating that the DHCPv6 client was already running. Collect all client unrefs in one place to unclutter the error handling. Fixes https://github.com/systemd/systemd/issues/963
