test/nvmf: add asynchronous NVMe initialization test

Browse Source 
The test verifies that the NVMe driver initialization is asynchronous.
There are some error logs during shutdown, as the detach path isn't
asynchronous yet, but as long as the detach is performed implicitly,
the test completes successfully.
