[BUG]filter test perfroms wrong when GDF_LESS_THAN

[StevenXJH]

filter_ops.cu
The comparison operations have bugs in the LESS_THAN condition, which makes it perform as same as the GREATER_THAN condition.

Code to reproduce bug
rapidsai/cudf/cpp/src/filter/filter_ops.cu: Line 62 &Line 72.
Both ">" should be "<".

Expected behavior
No mix between greater than and less than

Thanks @StevenJoker . filter_ops.cu is deleted by PR #1076 which is about to be merged. The functionality is replaced by binary operations. #892 has already been merged which implements that change. CC @devavret
