fabrics: add additional debug messages for --tls and --concat

Add additional debug messages when --tls and --concat is set
respectively based on the treq and sectype fields for a given record
in the discovery log page data during a nvme connect-all. This makes
it easier to debug, otherwise can be quite confusing to the end user.
