Yu Watanabe b425c3ae02 network: do not change to configuring state needlessly 
When DHCP or any other dynamic addresses are changed, then
link_request_set_routes() is invoked, and even if no static routes
are configured, the operational state is needlessly changed to
configuring state.
This makes the state is changed only when static routes are configured.

Yu Watanabe 463797c104 network: skip to check dynamic addresses when ConfigureWithoutCarrier=yes 
Otherwise, the interface cannot be in "configured" state, as ipv6 link local
addressing is enabled by default. Note that even if ConfigureWithoutCarrier=
is set, all dynamic configurations are checked when the interface has
carrier.
