[PATCH] nvmet: do not return 'reserved' for empty TSAS values

[Hannes Reinecke <hare@kernel.org>]

The 'TSAS' value is only defined for TCP and RDMA, but returning
'reserved' for undefined values tricked nvmetcli to try to write
'reserved' when restoring from a config file. This caused an error
and the configuration would not be applied.

Fixes: 3f123494db72 ("nvmet: make TCP sectype settable via configfs")
