double delete bug fixed

db name is printed with append_identifier for a proper quoting

  Correct the comment about the ibuf record format in >= 4.1.1

The problem was that memory was free'd, but it was referenced
later. This free was unneccessary anyway, because join_free() /
JOIN::cleanup takes care of this later on.

Added test case into t/subselect.test for it.
