net/mlx5: Prevent setting multicast macs for VFs
[ Upstream commit ccce1700263d8b5b219359d04180492a726cea16 ]
Need to check that VF mac address entered by the admin user is either
zero or unicast mac.
Multicast mac addresses are prohibited.
Fixes: 77256579c6b4 ('net/mlx5: E-Switch, Introduce Vport administration functions')
