Improving the time to wait for assigning IP address

Browse source 
Framework always spends 600msec for getting IP address.
DhcpStateMachine.runDhcp calls NetworkUtils.stopDhcp.
After that, it calls NetworkUtils.runDhcp.
In this case, wait_for_property of dhcp_utils.c calls three times.
At least three times, usleep is called.
So move usleep statement after property_get statement.
