Change bch_cached_dev_attach() to always wake up the writeback thread, because the newly created wb thread remains in uninterruptible sleep state until something explicitly wakes it up. This wakeup allows the thread to call bch_writeback_thread(), whereupon it will most likely end up in interruptible sleep. In theory we could just let the first write take care of this, but there's really no reason not to do the transition quickly.
