net/i40e/base: fix Rx only for unicast promisc on VLAN

Set promiscuous mode to rx traffic only if VSI has VLANs configured.
Rename misleading PROMISC_TX bit to proper name.
Added I40E_AQC_SET_VSI_PROMISC_RX_ONLY during VSI unicast promiscuous
mode configuration with port VLAN.
Aligned unicast promiscuous with VLAN to the one without VLAN.
Previously other VFs could listen to unicast tx traffic of other VFs.
