Fix code logic of setDHCPv6Property

When DHCP is IPv4 only, disabling DHCPv6 by calling setDHCPv6Property
will set DHCP to none, which also disables IPv4. This is an unexpected
behavior caused by current buggy code logic, there is no if condition
meets this situation, so the default value none will be used.

This patch fixes the issue by adopting the same logic as d5967afbbec5
("Fix unexpected change of ipsrc of ipv6").

Tested:
1. current=v4, requested=none => v4
2. Other cases work as expected
