Fix the issue as reported in (sonic-net#5315)

sonic-net#5255

Root Cause: Waiting on Restore count != 0 can lead to race condition
between orchagent process and swssconfig.sh.

Ideally check of  Restore count != 0 is not needed as the State DB
cannot be flushed as if it was flushed then Warm Restart or swss-restart
should not be true also.
