On our mlx5 driver fs_core.c, we use the rhltable interface to store flow groups. We noticed that sometimes we get a warning that flow group isn't found at removal. This rare case was caused when a specific scenrio happened, insertion of a flow group with a similar match criteria (duplicate), but only where the flow group rhash_head was second (or not first) on the relevant rhashtable bucket list.
The first patch fixes it, and the second one adds a test that show it is now working.
