Improve MAC address handling in mlx5_vdpa_set_attr() to ensure that old MAC entries are properly removed from the MPFS table before adding a new one. The new MAC address is then added to both the MPFS and VLAN tables. This change fixes an issue where the updated MAC address would not take effect until QEMU was rebooted.
