libata-pmp-prep: implement ATA_LFLAG_NO_RETRY
Some PMP links are connected to internal pseudo devices which may come and go depending on situation. There's no reason to try hard to recover them. ATA_LFLAG_NO_RETRY tells EH to not retry if the device attached to the link fails. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
