set_deparse_plan: Reuse variable to appease Coverity

Browse Source 
Coverity complains that dpns->outer_plan is deferenced (to obtain
->targetlist) when possibly NULL.  We can avoid this by using
dpns->outer_tlist instead, which was already obtained a few lines up.

The fact that we end up with
  dpns->inner_tlist = dpns->outer_tlist
is a bit suspicious-looking and maybe worthy of more investigation, but
I'll leave that for another day.
