bcache: move calculation of stripe_size and io_opt into bcache_device_init

bcache currently calculates the stripe size for the non-cached_dev
case directly in bcache_device_init, but for the cached_dev case it does
it in the caller.  Consolidate it in one places, which also enables
setting the io_opt queue_limit before allocating the gendisk so that it
can be passed in instead of changing the limit just after the allocation.
