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.
