block: move the io_stat flag setting to queue_limits
Move the io_stat flag into the queue_limits feature field so that it can
be set atomically with the queue frozen.
Simplify md and dm to set the flag unconditionally instead of avoiding
setting a simple flag for cases where it already is set by other means,
which is a bit pointless.
