i40evf: Fix a hardware reset support in VF driver
This patch fixes a hardware reset support in VF driver. It is needed because when a hardware reset is detected adapter->state is in __I40EVF_RESETTING state before i40evf_reset_task is called. Without this patch unloading VF driver after a hardware reset ends with a system crash.
