ec_sync: Reset EC after updating Hmir

This patch makes vb2api_sync_ec reset EC whenever Hmir is update because
the verification result should be revoked.

When Hmir is corrupted, the system enters NO_BOOT mode (and EC stays
in RO). Since Heff == Hexp, EC RW won't be updated but we need to
reset EC so that EC can jump to RW by EFS2.
