Title: rtl_test: Always step forward after finding a band edge.

PLL lock instability might produce inconsistent results for a particular frequency.
If we retest the same frequency and get different results, that can produce
spurious bands with start[n] == end[n] or end[n] == start[n+1]. Avoid that by always
moving forward once a band edge is found.
