[media] DVB: Delete an unnecessary check before the function call "dvb_unregister_device"
The dvb_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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
