quick-provision: Await reboot before doing post check.

Quick provisioning path was erroneously expecting PostCheckCrOSUpdate
to await for reboot, while in the non-quick provisioning cases this was
being done prior to that call.  This resulted in some race conditions
and a few attempts to work around it incorrectly.  Now, quick
provisioning can just call AwaitReboot which will ensure that the DUT
has rebooted before doing any other provisioning.
