Remove obsolete btrescan() comment.

"Ordering stuff" refered to a _bt_first() call to _bt_orderkeys().
However, the _bt_orderkeys() function was renamed to
_bt_preprocess_keys() by commit fa5c8a055a0.

_bt_preprocess_keys() is directly referenced just after the removed
comment already, which seems sufficient.
