net/mlx5e: Fix VLAN create flow
When interface is attached while in promiscuous mode and with VLAN filtering turned off, both configurations are not respected and VLAN filtering is performed. There are 2 flows which add the any-vid rules during interface attach: VLAN creation table and set rx mode. Each is relaying on the other to add any-vid rules, eventually non of them does. Fix this by adding any-vid rules on VLAN creation regardless of promiscuous mode.
