[PATCH] net/mlx5: fix the validation of the sample encap action

[PATCH] net/mlx5: fix the validation of the sample encap action

[Jiawei Wang]

The flow sample/mirror action includes sub-actions for the
duplicated packet.
In SW steering case, dv_flow_en=1, there is a FW limitation
that forces configuring also encap action when port action
for the wire port is configured in the duplicated packet's
sub-actions.

The driver did a wrong validation for the above limitation
and forced other actions instead of encap for the wire port.
Force only encap action in case of wire port.

This patch fixes the wrongly checking for the sample encap action.
