fabrics: add helper to update tls and concat

Only --tls was properly updated in nbft_connect(), and not
--concat. But this is properly done in nvmf_connect_disc_entry()
already. So add a helper function to update both --tls and
--concat and invoke the same from nvmf_connect_disc_entry() and
nbft_connect() respectively.
