bdev/nvme: don't connect to discovered discovery subsystems 



For now, if the discovery service finds a discovery subsystem,
don't connect to it.  Support for nested discovery controllers
will be coming soon, but for now we need to make sure we don't
try to connect to a discovery subsystem as if it was an NVM
subsystem.
