In particular, cache cntlid, nsze and ncap to make sure namespaces can be properly created and attached to. The test was assuming that the ns should be attached with a controllers' list always set to 0, however, that doesn't have to be the case for every nvme (the difference was noticed under SAMSUNG MZQL21T9HCJR-00A07). Same goes for the formatted block size where we cannot assume it's 512 bytes as it depends on the active lbaf.
