[PATCH 1/8 v3]reiserfs:stree.c Fix variable set but not used.

["Justin P. Mattock" <justinmattock@gmail.com>]

Resend of this patch due to previous whitespace issues and a messup
with v2.
The below fixes this warning:
fs/reiserfs/stree.c: In function 'search_by_key':
fs/reiserfs/stree.c:602:6: warning: variable 'right_neighbor_of_leaf_node' set but not used
