[SCTP]: Fix ia64 NaT consumption fault with sctp_sideffect commands.
On ia64, it is possible to get NaT Consumption Fault and a kernel panic
when initializing sctp sideeffect commands arguments. The union
sctp_arg_t contains different sized elements and when loading a smaller
sized element (32 or 16 bits), it is possible for a speculative load to
fail and result in a NaT bit set which causes a kernel crash. The easy
way to get around it is to load the largerst member of the union.
