i40e: Set RX_ONLY mode for unicast promiscuous on VLAN

[ Upstream commit 4bd5e02a2ed1575c2f65bd3c557a077dd399f0e8 ]

Trusted VF with unicast promiscuous mode set, could listen to TX
traffic of other VFs.
Set unicast promiscuous mode to RX traffic, if VSI has port VLAN
configured. Rename misleading I40E_AQC_SET_VSI_PROMISC_TX bit to
I40E_AQC_SET_VSI_PROMISC_RX_ONLY. Aligned unicast promiscuous with
VLAN to the one without VLAN.

Fixes: 6c41a7606967 ("i40e: Add promiscuous on VLAN support")
Fixes: 3b1200891b7f ("i40e: When in promisc mode apply promisc mode to Tx Traffic as well")
