Use 'break' instead of 'continue' in a 'do { } while (false)' loop.

In Source/WebCore/Modules/encryptedmedia/legacy/LegacyCDMSessionClearKey.cpp:

```
bool CDMSessionClearKey::update(Uint8Array* rawKeysData, RefPtr<Uint8Array>& nextMessage, unsigned short& errorCode, uint32_t& systemCode)
{
    [...]

    do {
        auto rawKeysString = String::fromUTF8(rawKeysData->data(), rawKeysData->length());
        if (rawKeysString.isEmpty())  {
            LOG(Media, "CDMSessionClearKey::update(%p) - failed: empty message", this);
            continue;
        }
        [...]
    } while (false);

    [...]
}
```
