There are two ways to check for I/O limits in a BlockDriverState: - bs->throttle_state: if this pointer is not NULL, it means that this BDS is member of a throttling group, its ThrottleTimers structure has been initialized and its I/O limits are ready to be applied. - bs->io_limits_enabled: if true it means that the throttle_state pointer is valid _and_ the limits are currently enabled. The latter is used in several places to check whether a BDS has I/O limits configured, but what it really checks is whether requests are being throttled or not. For example, io_limits_enabled can be temporarily set to false in cases like bdrv_read_unthrottled() without otherwise touching the throtting configuration of that BDS. This patch replaces bs->io_limits_enabled with bs->throttle_state in all cases where what we really want to check is the existence of I/O limits, not whether they are currently enabled or not.
