[media] siano: unnecessary check before rc_unregister_device() 

Author: Markus Elfring <elfring@users.sourceforge.net>

The rc_unregister_device() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.
