[Libreoffice] [PATCH] leaking connection handles

[Terrence Enger]

I offer the attached patch under LGPLv3+/MPL1.1 dual license
or future versions of the licenses,

It fixes a leak of connection handle in an ODBC database.
Without the call to SQLDisconnect90, SQLFreeHandle() fails
with code 'HY010'.

This is my first attempt a patch.  Comments and guidance
welcome.

Terry.
