Refresh Timestamp when pod is not present in the three sub-queues
...
The pInfo.Timestamp is refreshed but the sort in activeQ or podBackoffQ is not be updated when pod is already present in the backoff or active queue.
AddUnschedulableIfNotPresent() return error if pod is already present in the backoff or active queue, and there is no re-add.
So refresh pInfo.Timestamp when the pod is not present in the three sub-queues, otherwise need to update the order of the pod in the active or backoff queue, for example p.activeQ.Update(pInfo)

scheduler: fix flaky test TestPreemptionRaces
...
In some cases, an Update event with no "NominatedNode" present is received right
after a node("NominatedNode") is reserved for this pod in memory.
If we go updating (delete and add) it, it actually un-reserves the node since
the newPod doesn't carry sped.status.nominatedNode.
In this case, during this time other low-priority pods have chances to take space which
was reserved for the nominatedPod.

Ensure that pods obey backoff timers.
...
The function AddUnschedulableIfNotPresent is responsible for
initializing or updating backoff timers for pods that could not be
scheduled. The helper function backoffPod does that work, but was not
being called in all cases.
This moves that call to be (mostly) unconditional, while cleaning up
comments and error handling.
