[PATCH net v1] net/mlx5: Fix eswitch offloads cleanup on QoS init failure

[Prathamesh Deshpande]

If mlx5_esw_qos_init() fails after esw_offloads_init() succeeds,
mlx5_eswitch_init() jumps to reps_err and skips esw_offloads_cleanup(),
leaking the offloads initialization state.

Add a dedicated unwind label for QoS init failure that cleans up
offloads before continuing the existing vport and outer eswitch cleanup.

Fixes: cac7356c653d ("net/mlx5: Rework esw qos domain init and cleanup")
