Subject: [PATCH] Revert "wait for IPv6 RA if using none/static IPv6
 assignment"

This reverts commit c603419030136570b5944dc4620f62d07b9e82bb.

wait_for_ipv6_dad_link is only called from dhclient script,
so the original intent "wait for IPv6 RA if using none/static IPv6 assignment"
does not seem to be correct.

Anyway, this brings an issue on isolated networks, where you don't
have any routes outside. dhclient-script hangs on this check
and after it times out, dhclient is able to set the address normally.

(cherry picked from commit 76f6566fd777e0ee20416061ecb795e8daef33e1)

Resolves: #1795276
