block: move the stable_writes flag to queue_limits
Move the stable_writes flag into the queue_limits feature field so that
it can be set atomically with the queue frozen.
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.
