sd-dhcp6-client: fix sending prefix delegation request during rebind

Browse Source 
Fixes an assertion failure "pd->type == SD_DHCP6_OPTION_IA_PD" in dhcp6_option_append_pd().

Something similar was done in commit 26a63b8132 ('sd-dhcp6-client: Fix
sending prefix delegation request (#17136)'). The justification is
probably the same.

(cherry picked from commit 58da18251f)
