[media] hdpvr: hide unused variable
The i2c client pointer is only used when CONFIG_I2C is set, and otherwise produces a compile-time warning: drivers/media/usb/hdpvr/hdpvr-core.c: In function 'hdpvr_probe': drivers/media/usb/hdpvr/hdpvr-core.c:276:21: error: unused variable 'client' [-Werror=unused-variable] This uses the same #ifdef to hide the variable when the code using it is hidden.
