net/mlx5e: Use correct enum to determine uplink port

For vlan push action, if eswitch flow source capability is enabled, flow
source value compared with MLX5_VPORT_UPLINK enum, to determine uplink
port. This lead to syndrome in dmesg if try to add vlan push action.
For example:
 $ tc filter add dev vxlan0 ingress protocol ip prio 1 flower \
       enc_dst_port 4789 \
       action tunnel_key unset pipe \
       action vlan push id 20 pipe \
       action mirred egress redirect dev ens1f0_0
 $ dmesg
 ...
 [ 2456.883693] mlx5_core 0000:82:00.0: mlx5_cmd_check:756:(pid 5273): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xa9c090)
Use the correct enum value MLX5_FLOW_CONTEXT_FLOW_SOURCE_UPLINK.
