virtio-ccw has deadlock issues with reading the config space inside the

by moving the config read operations into the related workqueue contexts.
The config_read_bitmap is used as a flag to the workqueue callbacks
about the related config fields that need to be read.
The cmd_id_received is also renamed to cmd_id_received_cache, and
the value should be obtained via virtio_balloon_cmd_id_received.

OK. I don't plan to send a new version of the above patches as no
changes needed so far.
Michael, if the above two patches look good to you, please help add the
related tested-by
and reviewed-by tags. Thanks.
Best,
Wei
