Li Zefan 293f7e0740 Btrfs: zero unused bytes in inode item ...

The otime field is not zeroed, so users will see random otime in an old
filesystem with a new kernel which has otime support in the future.

The reserved bytes are also not zeroed, and we'll have compatibility
issue if we make use of those bytes.
