[PATCH] nilfs2: Remove an uninitialization warning innilfs_btree_propagate_v()

From: Li Hong
Date: Fri Apr 02 2010 - 06:40:56 EST

`make CONFIG_NILFS2_FS=m M=fs/nilfs2/` will give the following warnings:

fs/nilfs2/btree.c: In function ânilfs_btree_propagateâ:
fs/nilfs2/btree.c:1882: warning: âmaxlevelâ may be used uninitialized in this function
fs/nilfs2/btree.c:1882: note: âmaxlevelâ was declared here

Set maxlevel = 0 to fix it.
