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 scenario happened,
insertion of a flow group with a similar match criteria (a 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.

v4 --> v3 changes:
     * Added Herbert Xu's ack (thanks)
     * Removed extra commit tags

I already applied v3, sorry.  But I did add Herbert's ACKs.

thanks
