ASABASE-309 - Already persisted value is unnecessarily re-written to NVRAM during successful re-connection to Wi-Fi
1) Added a flag to indicate modification of the AJOBS_Info structure during the call to DoConnectWiFi().
2) Check whether the flag is set before calling AJOBS_SetInfo() to skip unnecessary writes.
