powerfail and add an exception to wolfBoot_delta_update when a revert gets

0th sector has been changed with the update partition still being in
IMG_STATE_UPDATING state. the state still being IMG_STATE_UPDATING means that a
delta update started and that the version may have been switched over, in which
case wolfBoot_current_firmware_version() >= wolfBoot_update_firmware_version()

also removes part of the update powerfail test that does checks for the
previous version without triggering a rollback
