[PATCH] uml ubd driver: give better names to some functions.
To rethink locking, I needed to understand well what each function does.
While doing this I renamed some:
* ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev)
* ubd_new_disk -> ubd_disk_register (it handles registration with the block
layer - one hopes this makes clearer the difference with ubd_add())
