ocfs2: correct return value of ocfs2_local_free_info()

Browse Source 
[ Upstream commit d32840ad4a ]

Now in ocfs2_local_free_info(), it returns 0 even if it actually fails.
Though it doesn't cause any real problem since the only caller
dquot_disable() ignores the return value, we'd better return correct as it
is.
