Move the io_stat flag into the queue_limits feature field so that it can

s/io_stat/stable_write

be set atomically and all I/O is frozen when changing the flag.

The flag is now inherited by blk_stack_limits, which greatly simplifies
the code in dm, and fixed md which previously did not pass on the flag
set on lower devices.

Other than the nit above, looks OK to me.
