Subject: [PATCH] When getting a new lease send the serverID and lease addr in a DHCP_REQUEST package.
Patch-Mainline: N/A

When a lease cannot be renewed dhcpclient tries to get a new lease starting
with a DHCP_DISCOVER. In this case the serverID and lease addr needs to be
sent in the DHCP_REQUEST package. This only happens when the if statement

      if (dhcp->address.s_addr &&
          dhcp->address.s_addr !=
          iface->previous_address.s_addr)
          {

is true. Thus iface->previous_address.s_addr needs to be when the lease
renewal fails and we reenter STATE_INIT.
