[IA64] Correct pernodesize calculation.

A simple fix.  The existing pernodesize reservation is not taking into
account a second array of pg_data_t structures.  This is normally not
important because the PAGE_ALIGN macro reserves adequate space.

I made the compute_pernodesize steps in the same order as the fill_pernode
steps to make the correlation more clear.
