media: dvb-usb: fix uninit-value in vp702x_read_mac_addr

Browse source

If vp702x_usb_in_op fails, the mac address is not initialized.
And vp702x_read_mac_addr does not handle this failure, which leads to
the uninit-value in dvb_usb_adapter_dvb_init.

Fix this by handling the failure of vp702x_usb_in_op.
