ide-tape: fix misprint in failure handling in idetape_init()
If driver_register() failed there is no sense to call driver_unregister(). unregister_chrdev() should be called here. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
