net/mlx5e: Unblock setting vid 0 for VF in case PF isn't eswitch manager

Browse Source 
[ Upstream commit 7846665d3504812acaebf920d1141851379a7f37 ]

When using libvirt to passthrough VF to VM it will always set the VF vlan
to 0 even if user didn’t request it, this will cause libvirt to fail to
boot in case the PF isn't eswitch owner.

Example of such case is the DPU host PF which isn't eswitch manager, so
any attempt to passthrough VF of it using libvirt will fail.

Fix it by not returning error in case set VF vlan is called with vid 0.
