Convert the remaining functions to make the QMP commands query-block
and query-named-block-nodes run in their entirety in a coroutine. With
this, any yield from those commands will return all the way back to
the main loop. This releases the BQL and the main loop and avoids
having the QMP command block another more important task from running.
Both commands need to be converted at once because hmp_info_block
calls both and it needs to be moved to a coroutine as well.
Now the wrapper for bdrv_co_get_allocated_file_size() can be made not
mixed and the wrapper for bdrv_co_block_device_info() can be removed.
