[CI] dropping XDR from ICS param attributes

[Aneesh K. <ane...@gm...>]

Hi John and Brian,

What is the specific requirment of using XDR within ICS. ? I see
structures like pt_regs being encoded using ics directly. As per our
last discussion most of these structures are marked OOL. So with XDR
we encode them with XDR routines and out then as OOL data. But then if
all the nodes involved in clustering are of same endian do we need to
encode them using XDR routines ?
