Don't create superblocks with size larger than SBSIZE (8192). The

Browse Source 
size was rounded up to a multiple of the fragment size, but this
gave invalid file systems when the fragment size was > SBSIZE (fsck
aborts early on them).  Now a fragment size of 32768 seems to work
(too-simple tests with fsck and iozone worked).
