- Round up the journal size to the block size so we don't confuse fsck.

Browse Source 
Reported by:	Mikolaj Golub <to.my.trociny@gmail.com>

 - Only require 256k of blocks per-cg when trying to allocate contiguous
   journal blocks.  The storage may not actually be contiguous but is at
   least within one cg.
 - When disabling SUJ leave SU enabled and report this to the user.  It
   is expected that users will upgrade SU filesystems to SUJ and want
   a similar downgrade path.
