media: dvb-usb: fix uninit-value in dvb_usb_adapter_dvb_init
If dibusb_read_eeprom_byte fails, the mac address is not initialized.
And nova_t_read_mac_address does not handle this failure, which leads to
the uninit-value in dvb_usb_adapter_dvb_init.
Fix this by handling the failure of dibusb_read_eeprom_byte.
