nvme: null terminate nvme_tls_attrs

Commit 1e48b34 ("nvme: split off TLS sysfs attributes into a
separate group") introduced the struct attribute array nvme_tls_attrs.
However, the array was not null terminated and caused BUG KASAN global-
out-of-bounds. To avoid the BUG, null terminate the array.
