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().
