Subject: net/mlx5: E-switch, Avoid function change handler for non ECPF
Patch-mainline: v5.9-rc1
Git-commit: 3d5f41ca01244fa2d261b76a0c728d6ac4526645
References: jsc#SLE-15172

for non ECPF eswitch manager function, vports are already
enabled/disabled when eswitch is enabled/disabled respectively.
Simplify function change handler for such eswitch manager function.

Therefore, ECPF is the only one which remains PF/VF function change
handler.
