HAMMER VFS - Force reading from the block device when live dedup is enabled
* Attempting to access the vnode's buffer cache is currently not MPSAFE
and can cause crashes so don't try to do that. Use the block device
instead.
* It is suggested but not required that vfs.hammer.double_buffer mode also
be enabled if you use vfs.hammer.live.deup.
