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