Block devices have an individual active state, a single global flag can't cover this correctly. This becomes more important as we allow users to manually manage which nodes are active or inactive. Now that it's allowed to call bdrv_inactivate_all() even when some nodes are already inactive, we can remove the flag and just unconditionally call bdrv_inactivate_all() and, more importantly, bdrv_activate_all() before we make use of the nodes.
