Value of leased-address while processing DISCOVER

[Glenn Satchell]

The value of leased-address varies depending on whether the server is
handling a DHCPDISCOVER, DHCPREQUEST, etc.

You can test the value of 'option dhcp-message-type' (see dhcp-options
man page for possible values) to see whether leased-address is likely
to be valid or not.
