Currently ipr always returns success from eh_dev_reset when
called for a SATA device. If ata_do_eh is unable to recover
for some reason, this can result in commands that are still
outstanding when ata_do_eh returns. Change ipr to verify no
commands are outstanding before returning success.

James,
Looks like this one got dropped. This is a resend.
Thanks,
