Alexey Khoroshilov 9a32bb39d6 ppdev: ppdev_init: do not return zero in case of failure 
Error handling of parport_register_driver() in ppdev_init()
is broken because it deallocates all resources but still
returns zero.

Currently parport_register_driver() always succeeds.
Nevertheless it is worth to fix the issue.
