media: dvb-usb: dw2102: fix uninit-value in su3000_read_mac_address
[ Upstream commit a3fd1ef27aa686d871cefe207bd6168c4b0cd29e ]
In su3000_read_mac_address, if i2c_transfer fails to execute two
messages, array mac address will not be initialized. Without handling
such error, later in function dvb_usb_adapter_dvb_init, proposed_mac
is accessed before initialization.
Fix this error by returning a negative value if message execution fails.
