Remove call to DeriveKeys for release

Merge of http://go/wvgerrit/45520/

Bug: b/70650789

Test: request_license_tests and GTS tests on sailfish and taimen

This is related to b/70650789. An extra call to DeriveKeysFromSessionKey
in the case where there is a provider session token results in the
OEMCrypto mock incorrectly using the derived mac keys to sign the release
message, since a future call to LoadKeys is never called.
