libata: don't whine if ->prereset() returns -ENOENT
->prereset() returns -ENOENT to tell libata that the port is empty and reset sequencing should be stopped. This is not an error condition. Update ata_eh_reset() such that it sets device classes to ATA_DEV_NONE and return success in on -ENOENT. This makes spurious error message go away.
