bdrv_can_store_new_dirty_bitmap and bdrv_remove_persistent_dirty_bitmap check if they are running in a coroutine, directly calling the coroutine callback if it's the case. Except that no coroutine calls such functions, therefore that check can be removed, and function creation can be offloaded to g_c_w_simple.
