[PATCH] libata: implement ata_dev_revalidate()
ata_dev_revalidate() re-reads IDENTIFY PAGE of the given device and
makes sure it's the same device as the configured one. Once it's
verified that it's the same device, @dev is configured according to
newly read IDENTIFY PAGE. Note that revalidation currently doesn't
invoke transfer mode reconfiguration.
Criteria for 'same device'
* same class (of course)
* same model string
* same serial string
* if ATA, same n_sectors (to catch geometry parameter changes)
