net/mlx5: DR, Align mlx5dv_dr API vport action with FW behavior

Browse Source 
[ Upstream commit aa818fbf8f ]

This aligns the behavior with FW when creating an FDB rule with wire
vport destination but no source port matching. Until now such rules
would fail on internal DR RX rule creation since the source and
destination are the wire vport.
The new behavior is the same as done on FW steering, if destination is
wire, we will create both TX and RX rules, but the RX packet coming from
wire will be dropped due to loopback not supported.
