Gets the unwind action address, if there is one, in the UnwindMapEntry 
indicated by the ordinal.
@param unwindOrdinal 0-based ordinal indicating which UnwindMapEntry in the map.
@return the unwind action address or null.
@throws InvalidDataTypeException if valid UnwindMapEntry data can't be created for 
the indicated ordinal.
