blockdev: Allow creation of BDS trees without BB
If the "id" field is missing from the options given to blockdev-add,
just omit the BlockBackend and create the BlockDriverState tree alone.
However, if "id" is missing, "node-name" must be specified; otherwise,
the BDS tree would no longer be accessible.
Many BDS options which are not parsed by bdrv_open() (like caching)
cannot be specified for these BB-less BDS trees yet. A future patch will
remove this limitation.
