rbd: a few simple changes
Here are a few very simple cleanups:
- Add a "RBD_" prefix to the two driver name string definitions.
- Move the definition of struct rbd_request below struct rbd_req_coll
to avoid the need for an empty declaration of the latter.
- Move and group the definitions of rbd_root_dev_release() and
rbd_root_dev, as well as rbd_bus_type and rbd_bus_attrs[],
close to the top of the file. Arrange the latter so
rbd_bus_type.bus_attrs can be initialized statically.
- Get rid of an unnecessary local variable in rbd_open().
- Rework some hokey logic in rbd_bus_add_dev(), so the value of
"ret" at the end is either 0 or -ENOENT to avoid the need for
the code duplication that was there.
- Rename a goto target in rbd_add().
