Commit 3f342839 corrected obsolete comments about buffer locks at the main _bt_insert_parent() call site, but missed similar obsolete comments above _bt_insert_parent() itself. Both sets of comments were rendered obsolete by commit 40dae7ec537, which made the nbtree page split algorithm more robust. Fix the comments that were missed the first time around now. In passing, refine a related _bt_insert_parent() comment about re-finding the parent page to insert new downlink.
