libata: assume no device is attached if both IDENTIFYs are aborted upstream commit: 1ffc151fcddf524d0c76709d7e7a2af0255acb6b This is to fix bugzilla #10254. QSI cdrom attached to pata_sis as secondary master appears as phantom device for the slave. Interestingly, instead of not setting DRQ after IDENTIFY which triggers NODEV_HINT, it aborts both IDENTIFY and IDENTIFY PACKET which makes EH retry. Modify EH such that it assumes no device is attached if both flavors of IDENTIFY are aborted by the device. There really isn't much point in retrying when the device actively aborts the commands. While at it, convert NODEV detection message to ata_dev_printk() to help debugging obscure detection problems. This problem was reported by Jan Bücken.
