[PATCH] ide-scsi: fix for IDE probe/remove ops changes

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to. It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.

The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct. drivers/ide/ was updated for this
change but ide-scsi.c wasn't. Hence the breakage.

This patch repairs ide-scsi and also eliminates the driver core warning.
