Correct offline license handling

Browse Source 
[ Merge of http://go/wvgerrit/28261 ]

Licenses (offline, secure stops) that contain provider session tokens
are handled securely using usage tables. A recent fix did not correctly
handle offline licenses that do not contain a provider session token and
are not handled by the TEE.
