[PATCH] nilfs2: Remove an uninitialization warning in nilfs_btree_propagate_v()

[PATCH] nilfs2: Remove an uninitialization warning in nilfs_btree_propagate_v()

[Li Hong]

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

fs/nilfs2/btree.c: In function ‘nilfs_btree_propagate’:
fs/nilfs2/btree.c:1882: warning: ‘maxlevel’ may be used uninitialized in this function
fs/nilfs2/btree.c:1882: note: ‘maxlevel’ was declared here

Set maxlevel = 0 to fix it.
