net/mlx5e: Fix null pointer access when setting MTU of vport representor

Browse source

MTU helper function is used by both conventional mlx5e
instances (PF/VF) and the eswitch representors. The representor
shouldn't change the nic vport context MTU, the VF is responsible for
that. Therefore set_mtu_cb has a null value when changing the
representor MTU.
