Fix for rtlsdr_set_tuner_if_gain()

Hi,

I've now pushed a change to librtlsdr that disables the AGC by default, and added the function rtlsdr_set_agc_mode() that can be used to re-enable it again.

This works well. I use rtlsdr_set_tuner_if_gain() now to compensate for the gain loss and found a bug there: The i2c repeater needs to be enabled.
