net/mlx5e: Release skb in case of failure in tc update skb

Browse source 
In case of failure in tc update skb the packet is dropped
without freeing the skb.

Fixed by freeing the skb in case failure in tc update skb.

Fixes: d6d2778286 ("net/mlx5: E-Switch, Restore chain id on miss")
Fixes: c756909722 ("net/mlx5e: Add tc chains offload support for nic flows")
