ide: remove IDE devices from /proc/ide/ before unregistering them
IDE devices need to be removed from /proc/ide/ _before_ being unregistered:
* Drop 'ide_hwif_t *hwif' argument from destroy_proc_ide_device()
and use drive->hwif instead.
* Rename destroy_proc_ide_device() to ide_proc_unregister_device().
* Call ide_proc_unregister_device() in drive_release_dev().
* Remove no longer needed destroy_proc_ide_drives().
