In case some module has `async_init = true` and
some other module that comes after it fails to initialize,
then callback from asynchronously initialized module
may call `spdk_bdev_init_complete()` first, then failed module
will call `spdk_bdev_init_complete()` later.
This currently results in NULL dereference because
first call to `spdk_bdev_init_complete()` sets `g_init_cb_fn = NULL`.
This change prevents first call to `spdk_bdev_init_complete()`
by saying that failed module is not finished with initialization.
This patch fixes#847
