examples: Fix tx_bursts bandwidth/freq/gain reporting

This example would not specify a channel when querying the actual
frequency/bandwidth/gain after setting it. When using the --channels
options like this:

    tx_bursts --channels 1 --freq 1e9 [...]

...it would request the frequency of 1 GHz on channel 1, then query the
frequency on channel 0 when reporting the "actual" frequency.

Also removes some boost::format().
