So, if there are real consequences, we can definitely add a way to
short-circuit the recovery logic but let's do that by adding proper

In ata_eh_reset, it will reset three times at most for sata disk. For
some drivers through libsas, it calls sas_ata_hard_reset at last. When
device is gone, function sas_ata_hard_reset will return -ENODEV. But
it will still try to reset three times for offline device. This process
lasts a long time
