Keep track of all request_queues which have blkcg initialized and turn on bypass and invoke blkcg_clear_queue() on all before making changes to blkcg policies. This is to prepare for moving blkg management into blkcg core. Note that this uses more brute force than necessary. Finer grained shoot down will be implemented later and given that policy [un]registration almost never happens on running systems (blk-throtl can't be built as a module and cfq usually is the builtin default iosched), this shouldn't be a problem for the time being.
