If VF device is used as slave of a bond device, it will be polled
periodically through alarm. Interrupt is involved here. And then
VF will send I40E_VIRTCHNL_OP_GET_LINK_STAT message to
PF to query the status. The response is handled by interrupt
callback. Interrupt is involved here again. That's why bond
device cannot bring up.
This patch removes I40E_VIRTCHNL_OP_GET_LINK_STAT
message. Link status in VF driver will be updated when PF driver
notify it, and VF stores this link status locally. VF driver just
returns the local status when being required.
