libata: improve probe failure handling
* Move forcing device to PIO0 on device disable into
ata_dev_disable(). This makes both old and new EHs act the same
way.
* Speed down only PIO mode on probe failure. All commands used during
probing are PIO commands. There's no point in speeding down DMA.
* Retry at least once after -ENODEV. Some devices report garbled
IDENTIFY data after certain events. This shouldn't cause device
detach and re-attach.
* Rearrange EH failure path for simplicity.
