Log Message:
Initialize DAD components properly

The original code initialized each component in non-init functions such as
arp_dad_start and nd6_dad_find, conditionally based on a global flag for each.
However, it was racy because the flag and the code around it were not
protected by a lock and could cause a kernel panic at worst.

Fix the issue by initializing the components in bootup as usual.
