      Bug#33717 INSERT...(default) fails for enum. Crashes CSV tables, loads spaces for MyISAM
      Table corruption happens during table reading in ha_tina::find_current_row() func.
      Field::store() method returns error(true) if stored value is 0, but 0 is legal value.
      The fix is to return false if the value is 0.
      Additional fix:
        INSERT...(default) and INSERT...() have the same behaviour now.

    test case
  sql/field.cc
    0 is legal value for ENUM type, so there is
    no need to return error in this case(except the strict mode).
    If strict mode is enabled then return error.
  sql/item.cc
    set default value
  sql/sql_insert.cc
    removed check for ENUM field. The reason is that
    ENUM field behavoir should be the same as other
    fileds have.
