fix Gather op's incorrect gradient value.
 
* the error was due to that we pad 0 as default value for missing gaps. All these then each contribute 1 to the gradient of reference at index 0. The fix is to mask missing values in indices matrix to negative, and in Matrix scatter implementation to check and skip negative indices. (previous Matrix CPU implementation already checks for negative indices)
