[dts] [PATCH V2] fix vlan filter off in invalid

[xu,gang]

Before the dpdk commit 8b9bd0efe0b6920a08e28eebacf2bb916bdf5653
VLAN filter and VLAN strip are enabled in testpmd by default.
But since this commit ,they are disabled by default.
so "vlam set filter off 0" can't be expected, need "vlan set filter on 0" first
