nvme in-band authentication blktests - nvme/043

[alan.adamson@oracle.com]

I'm playing around with in-band authentication and using blktests to see 
how to setup it up and use it.  In test nvme/043, a valid hostkey is 
never initialized and a NULL is being used to setup the target and to 
connect.  Is this expected?  The test with the NULL hostkey passes.  I 
updated the test to use a valid key and it also passes.
