i40e: Bypass timeout recovery level 0 so as to not cause MDD
When a Tx hang happens, usually the Tx queue disable fails. At
this point if we try to recover by a VSI reinit the HW gets
unhappy and we get a Malicious Driver Detect (MDD) event.
HW expects a PF reset if a queue disable fails, if we don't do a PF
reset and restart the queue we get an MDD. This patch makes sure we
do a PF reset on Tx hang and that way we avoid any MDD because of Tx
queue disable failure.
