crypto: jitter - correct health test during initialization
With the update of the permanent and intermittent health errors, the actual indicator for the health test indicates a potential error only for the one offending time stamp gathered in the current iteration round. The next iteration round will "overwrite" the health test result. Thus, the entropy collection loop in jent_gen_entropy checks for the health test failure upon each loop iteration. However, the initialization operation checked for the APT health test once for an APT window which implies it would not catch most errors. Thus, the check for all health errors is now invoked unconditionally during each loop iteration for the startup test. With the change, the error JENT_ERCT becomes unused as all health errors are only reported with the JENT_HEALTH return code. This allows the removal of the error indicator.
