[S390] tape: cleanup reference counting
Rename tape_get_device to tape_find_device and tape_get_device_reference to tape_get_device. The old names didn't make too much sense. Follow the get_device()/put_device() semantic and convert tape_put_device to a void function. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
