net/i40e: fix queue related exception handling

There should have different behavior in queue start fail and stop fail
case.  When queue start fail, all the next actions should be terminated
and then started queues should be cleared. But for queue stop stage, one
queue stop fail should not end other queues stop. This patch fixed that
issue in PF and VF.
