net/iavf: fix VF reset

Browse Source 
When the VF is in closed state, the vf_reset flag can not be reverted
if the VF is reset asynchronously. This prevents all virtchnl commands
from executing, causing subsequent calls to iavf_dev_reset() to fail.

So the vf_reset flag needs to be reverted even when VF is in closed state.
