In case of the known issue, that DPDK PHY config can't synchronous with
kernel driver and firmware, this will result of the nic can't link up
after rebind to the kernel driver. This patch propose to work around it
by don't config PHY and don't set link down when stop device.

Fixes: 6e145fcc754b ("i40e: support autoneg or force link speed")
