Subject: [PATCH] Fix offline key restoration failures

[Merge of https://widevine-internal-review.googlesource.com/#/c/14110/ from
 widevine cdm repo]

Backward compatibility handling was causing L3 usage and clock information
to be moved. This caused nonce and other failures when attempting to restore
offline keys.
