mxl111sf: Fix unintentional garbage stack read
commit 866e8d8a9dc1ebb4f9e67197e264ac2df81f7d4b upstream. mxl111sf_read_reg takes an address of a variable to write to as an argument. drivers/media/usb/dvb-usb-v2/mxl111sf-gpio.c:mxl111sf_config_pin_mux_modes passes several uninitialized stack variables to this routine, expecting them to be filled in. In the event that something unexpected happens when reading from the chip, we end up doing a pr_debug of the value passed in, revealing whatever garbage happened to be on the stack. Change the pr_debug to match what happens in the 'success' case, where we assign buf[1] to *data.
