Fix testing of parallel-safety of scan/join target.

In commit960df2a ("Correctly assess parallel-safety of tlists whenSRFs are used."), the testing of scan/join target was done incorrectly,which caused a plan-quality problem. Backpatch through to v11 wherethe aforementioned commit went in, since this is a regression from v10.Author: Etsuro FujitaReviewed-by: Robert Haas and Tom LaneDiscussion:https://postgr.es/m/5C75303E.8020303@lab.ntt.co.jp
