block: update the stable_writes flag in bdev_add
Propagate the per-queue stable_write flags into each bdev inode in bdev_add.
This makes sure devices that require stable writes have it set for I/O
on the block device node as well.
Note that this doesn't cover the case of a flag changing on a live device
yet. We should handle that as well, but I plan to cover it as part of a
more general rework of how changing runtime paramters on block devices
works.
Fixes: 1cb039f3dc16 ("bdi: replace BDI_CAP_STABLE_WRITES with a queue and a sb flag")
