The error code OEMCrypto_KEY_NOT_LOADED is redundant with
OEMCrypto_ERROR_NO_CONTENT_KEY and OEMCrypto_KEY_NOT_ENTITLED.  The
function LoadEntitledContentKey should return KEY_NOT_ENTITLED if it
does not find the corresponding entitlement key in its key table.  All
other functions that do not find a key id in the key table should
return OEMCrypto_ERROR_NO_CONTENT_KEY.  This includes QueryKeyControl,
SelectKey, and RefreshKeys.

Test: unit tests
Test: tested as part of http://go/ag/5501993
