Cherry-pick: Skip tearDownInterfaces during init

CleanUpSystemState is called when wificond starts, so we can skip
tearDownInerfaces call as long as wificond is restart.
This helps to save the WiFi service start time from 291ms to 57ms
measured on marlin.

Bug: 33752168
Test: wificond_unit_test and  wificond_integration_test passed
