Eventually that will be the right thing, but only after we allocate
bd_inode upon blkdev_get()/blkdev_open() instead of trying to cannibalize
the inode passed to blkdev_open().

I'm testing that chunk right now (it also kills all the fake_inode crap in

When we cut the lifetime of block_device down we'll be able to get it
even simpler - allocate and free ->bd_inode at the same time as block_device,
but that's several chunks later.
