Currently, in the Rx data path cookie conversion initialization procedure,
the primary page table index (ppt_idx) is computed within the secondary
page table iteration. However this is invariant, and hence the ppt_idx
should be calculated outside of the iteration to avoid repeated execution
of the statement.
Found in code review.
