  Bug#19182: CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work
             from stored procedure.
  
  The cause of a bug was that cached LEX::create_list was modified, and
  then together with LEX::key_list was reset.

    Chop off extra fields added to field list, so that original field list
    will stay unmodified after the call.
