Theoretically, multiple withdraw from the best feed should never happen
but apparently there is an opportunity. We are unable to reproduce that
but it's obvious that with the old code, if the last ROA to remove is at
the end of the list, an undefined memory is checked. If it accidentally
matches (which seems to be pretty rare), BIRD may call memcpy() with
a negative length and subsequently crash on segfault.
