ocfs2/xattr: Remove extend_trans call and add its credits from the beginning
Actually, when setting a new xattr value, we know it from the very beginning, and it isn't like the extension of bucket in which case we can't figure it out. So remove ocfs2_extend_trans in that function and calculate it before the transaction. It also relieve acl operation from the worry about the side effect of ocfs2_extend_trans.
