Btrfs: fix wrong return value of btrfs_truncate_page() ret variant may be set to 0 if we read page successfully, but it might be released before we lock it again. On this case, if we fail to allocate a new page, we will return 0, it is wrong, fix it. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
