[PATCH] libata-hp-prep: store attached SCSI device
Add device persistent field dev->sdev and store the attached SCSI
device. With hotplug, libata needs to know the attached SCSI device
to offline and detach it, but scsi_device_lookup() cannot be used
because libata will reuse SCSI ID numbers - dead but not gone devices
(due to zombie opens, etc...) interfere with the lookup.
dev->sdev doesn't hold reference to the SCSI device. It's cleared
when the SCSI device goes away.
