Fix KM3.0 deleteKey behavior inconsistent with VTS test.
Keymaster 3.0 VTS test required that deleteKey returns
ErrorCode::OK even if the key blob parameter is invalid or garbage.
The rationale is that deleteKey shall have the invariant that
key blobs are unusable after the deleteKey call. If it was unusable
before, this invariant is upheld.
This patch makes the legacy wrapper for the Keymaster HAL translate
an ErrorCode::INVALID_KEY_BLOB retuned by the legacy delete_key to
ErrorCode::OK.
Bug: 37351644
Test: Manually run VtsHalKeymasterV3_0TargetTest with legacy keymaster
HAL installed (tested with sailfish)
