QT GUI Frequency Sink and real inputs labels are wrong for FFT length != 1024

If one selects real input on a QT GUI Frequency sink, and also selects
half-width, and also has an FFT size != 1024, then the X-axis labels are
wrong.

If using an FFT length of 1024, the X axis labels proceed from 0 to
bandwidth/2, as one might expect. I tried playing with the “center
frequency”
parameter to make the labels make sense, but I couldn’t find a setting
that made it better…
