Improve ata_reinit():

 - protect againtst recursions,
 - add new devices detection using ata_identify().

Improve ata_identify():
 - do not add duplicate device if device already exist.

Rework SATA hot-plug events handling. Instead of unsafe duplicate
implementation use common ata_reinit() to handle all state changes.

All together this gives quite stable and robust cold- and hot-plug operation,
invariant to false, lost and duplicate events.
