Subject: [net 01/12] net/mlx5: Fix memory leak on flow table creation error flow

From: Roi Dayan <roid@...dia.com>

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")
