Fixed Bug#2479, "dependant subquery with limit crash".

Browse Source 
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.

Regards,
Jani
