[PATCH] net/iavf: fix issue of VF resetting

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.
Fixes: 676d986b4b86 ("net/iavf: fix crash after VF reset failure")
