This reverts commit 24599af599acf74b71a555a8eeb827bedcd672b5.

Reason for revert: b/173009837

Test: 1. update_device.py ota.zip
--extra-headers="SWITCH_SLOT_ON_REBOOT=0"
      2. update_device.py ota.zip
      3. Verity that 2 did not re-start the entire update, only fs
                  verification and postinstall may re-run.
