tree: avoid updating --tls in nvme_read_sysfs_tls()

It is wrongly assumed that the presence of the sysfs tls_key
attribute in nvme_read_sysfs_tls() indicates --tls was invoked.
But this can also happen if --concat was invoked as well. And both
--tls and --concat are mutually exclusive. So avoid explicitly
setting --tls again here, since both --tls & --concat already
appropriately set earlier in the workflow.
