Subject: [PATCH] Sony Patch to LicenseKeys::GetAllowedUsage()

Merged from http://go/wvgerrit/175350.

Sony has identified a 5-year-old copy-and-paste error in
LicenseKeys::GetAllowedUsage(). For entitled keys, it was calling
CanDecryptContent() instead of GetAllowedUsage() on the entitlement key
session. This meant that for entitled keys, the allowed_usage parameter
was never updated and the return value of the function was indicating
something different than intended.
