[-mm patch] fs/reiser4/: more possible cleanups

[Adrian Bunk <bunk@stusta.de>]

This patch contains the following possible cleanups:
- make needlessly global functions static
- #if 0 unused functions
- #if REISER4_DEBUG functions that are only used with debugging enabled

Signed-off-by: Adrian Bunk <bunk@stusta.de>
