callback.c : fallback to normal download with bogus size

When using totaldownload, we might get into some weird situations where
xfered>total because of bogus CSIZE database entries.

This code adds a sanity check and fallbacks to normal download progress if
needed.

Here is an example using totaldownload on a database with wrong CSIZE, for a
total download of ~26 MB.

Note that gnome-control-center resetted to normal progress mode
(2,5M is the package size, not the total size)
