This reverts commit0dba1314d4. It causes leaking of device numbers for SCSI when SCSI registers multiple gendisks for one request_queue in succession. It can be easily reproduced using Omar's script [1] on kernel with CONFIG_DEBUG_TEST_DRIVER_REMOVE. Furthermore the protection provided by this commit is not needed anymore as the problem it was fixing got also fixed by commit165a5e22fa"block: Move bdi_unregister() to del_gendisk()".
