net: tls: reshuffle the device ops check

We try to validate during registration that the netdev
has ops if it has features. This is currently somewhat sillily
written because we have a dereference before a NULL check
on the ops struct. Straighten this out.

No functional change intended other than saving ourselves
the very theoretical crash with a bad driver.

Note that we check earlier in the function that either ops
or TLS features are set for the device in question.
