Subject: net/mlx5: Fix memory leak on flow table creation error flow
Git-commit: 487c6ef81eb98d0a43cb08be91b1fcc9b4250626
Patch-mainline: v5.11-rc6
References: bsc#1046305 FATE#322943

When we create the ft object we also init rhltable in ft->fgs_hash.
So in error flow before kfree of ft we need to destroy that rhltable.

Fixes: 693c6883bbc4 ("net/mlx5: Add hash table for flow groups in flow table")
