[PATCH 2/7] [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.
