Ignore certain errors on RemoveOfflineLicense().

[ Merge of http://go/wvgerrit/210652 ]

The CDM API RemoveOfflineLicense() is used to remove an offline
license by key set ID.  From the app's perspective, removing the
offline license should not depend on an app to be provisioned, or
the license being loadable.  However, internally, the CDM attempts
to restore the license to lock out its usage entry.

An issue arises when the license is not able to be restored, which
will cause errors related to the restoration to be returned to the
app.  The license is still deleted in case of errors, but certain
partners have experienced GTS failures when using the MediaDRM API
removeOfflineLicense().

This change attempts to catch some of the common errors, but not all.
If certain errors are encountered during the restoration process, the
are not returned to the app.

Additional error cases may be added later, depending on vendor
feedback.
