## Description 

In #14087, we thought it is ok to set the processed bit for every
transaction in the consensus output. But it turns out setting ignored
transaction to `processed` may prevent reverting transactions, if a
validator restarts during epoch change.

This change only avoid setting the `processed` bit for ignored
transactions. It does not completely restore the behavior before #14087.

## Test Plan 

Ran on `simtest-01` CI machine:
```
SIM_STRESS_TEST_DURATION_SECS=300  USE_MOCK_CRYPTO=1 MSIM_TEST_NUM=60 cargo simtest test_simulated_load_reconfig_with_crashes_and_delays
```
