Fix for memory leak in 64 bit ODBC driver's call to SQLGetStmtAttr()
Windows API call to SQLGetStmtAttr() attempts to place an 8 byte value
into the isScrollable variable which of type SQLINTEGER which is a long
and is 32 bit on Windows even when the driver is compiled for 64 bit.
Changing the isScrollable to and 8 byte SQLULEN type.
