pim6d: Do not use interfaces with ifindex as 0

After restarting pim6d, in some cases the ifindex is 0 for the interfaces,
so the vif index is also assigned as 0.
This causes the interface name to be pim6reg.

Fix:
If the ifindex is 0 and the interface name is not "pimreg" or "pim6reg",
the function will return without assigning vifindex with an error message.

Issue: #12744
