nbd: use bd_set_size when updating disk size
When we stopped relying on the bdev everywhere I broke updating the
block device size on the fly, which ceph relies on. We can't just do
set_capacity, we also have to do bd_set_size so things like parted will
notice the device size change.
Fixes: 29eaadc ("nbd: stop using the bdev everywhere")
