test/ftl: wait till nbd is ready when loading JSON config

Browse Source 
When creating the nbd, we wait until it's ready, but we didn't do
that when loading the configuration from JSON, which resulted in
sporadic IO failures, as the device hasn't been initialized yet. This
patch adds waitfornbd after each load_config call.
