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.
