[media] au0828: fix checks if dvb is initialized

dev->dvb is always not null, as it is an area at the dev
memory. So, checking if (dev->dvb) is always true.

Instead of this stupid check, what the code wants to do is
to know if the DVB was successully registered.

Fix it by checking, instead, for dvb->frontend. It should
also be sure that this var will be NULL if the device was
not properly initialized.
