bfs: check that filesystem fits on the blockdevice

Since all sanity checks rely on the validity of s_start which gets only
checked to be smaller than s_end, we should also check if s_end is sane.
Now we also try to retrieve the last block of the filesystem, which is
computed by s_end.  If this fails, something is bogus.
