When we use laser_filters/LaserScanIntensityFilterwith gazebo, this will die because overflowed value is passed to array index around https://github.com/ros-perception/laser_filters/blob/indigo-devel/include/laser_filters/intensity_filter.h#L96-L99

So I added to check the value of intensities and do min compare to prevent overflowed int generating.
