btrfs: Use bd_dev to generate index when dev_state_hashtable add items.
Fix missing change from commit f8f84b2dfda5 ("btrfs: index check-integrity state hash by a dev_t"). Function btrfsic_dev_state_hashtable_lookup uses dev_t to generate hashval when look in up a btrfsic_dev_state in hash table. So when we add a btrfsic_dev_state into the hash table, it should also use dev_t. Reproducer of this bug: Use MOUNT_OPTIONS="-o check_int" when running xfstest, device can not be mounted successfully. So xfstest can not run.
