Subject: Remove unnecessary assignment of path rows in gather merge
The number of rows of a gather merge node is set inside
cost_gather_merge, making the assignment in create_gather_merge_path
unnecessary and slightly misleading.
This patch removes the unnecessary assignment from
create_gather_merge_path, mirroring what's done in create_gather_path.
