ext4: Use a fake block number for delayed new buffer_head

(cherry picked from commit 33b9817e2ae097c7b8d256e3510ac6c54fc6d9d0)

Use a very large unsigned number (~0xffff) as as the fake block number
for the delayed new buffer. The VFS should never try to write out this
number, but if it does, this will make it obvious.
