Subject: [PATCH 2/3] fs/ufs: re-arrange the code a bit

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

This patch does not do any functional changes. It only moves 3 functions
in fs/ufs/super.c a little bit up in order to prepare for further changes
where I'll need this new arrangement to avoid forward declarations.
