memory leak in ODBC driver

There is a 16-byte leak for every statement handle that has SQLFetch called on it.
I have tracked this leak down to its source:
SC_Fetch calls extend_getdata_info, which allocates memory for the stmt.getdata_info.
However, this memory is never freed when the statement is deallocated.

This patch seems to fix the problem - however I don't know enough about the internals of the driver to really understand if this is the correct or safe fix.
Can one of the developers help me out here?
