fix(scan_ground_filter): fix segmentation fault

[miursh]

Description

Fix segmentation fault due to access violation in out_radial_ordered_points[radial_div]

Test procedure

Run rosbag replay simulation with sample-bag and other rosbags to verify that the scan ground filter is not terminated.
Tested with rosbag, which was causing the segmentation fault, and confirmed that there was no problem.

I confirmed this node is not terminated and works well with rosbag replay simulation.
