When configuring TC-MQPRIO offload, only turn off netdev carrier and
don't bring physical link down in hardware. Otherwise, when the
physical link is brought up again after configuration, it gets
re-trained and stalls ongoing traffic.
Also, when firmware is no longer accessible or crashed, avoid sending
FLOWC and waiting for reply that will never come.
Fix following hung_task_timeout_secs trace seen in these cases.
