[ Upstream commit 797c061ad715a9a1480eb73f44b6939fbe3209ed ]
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.

Since the first version of this driver, the remote controller
code is disabled, adding an early return inside vp702x_rc_query().
Let's disable the code with #if 0, to remove this warning:
drivers/media/usb/dvb-usb/vp702x.c:268 vp702x_rc_query() info: ignoring unreachable code.

As media/dvb will be removed, move it to a proper place.
