Postcopy (in failure path) should share with precopy on disk reactivations.
Explicit activiation should used to be fine even if called twice, but after
26f65c01ed ("migration: Do not try to start VM if disk activation fails")
we may want to avoid it and always capture failure when reactivation
happens (even if we do not expect the failure to happen).  Remove this
redundant call.
