mas_extend_spanning_null() was not modifying the range min and range max of the resulting store operation. The result was that the maple write state no longer matched what the write was doing. This was not an issue as the values were previously not used, but to make the ma_wr_state usable in future changes, the range min/max stored in the ma_wr_state for left and right need to be consistent with the operation.
