In renewal, clients are required to set ciaddr, and required not to
set the DHCP option 'dhcp-requested-address' (RFC2131 section 4.3.2,
but 4.3.6 has a table that is easier to read).

Sounds normal to me.  The patch to include the requested address is
clearly wrong; the correct approach is to use ciaddr if nonzero and
requested-address otherwise.
