Handle an invalid new frame request

When HalCamera and VirtualCamera are synchronized based on the fences,
it is possible that VirtualCamera sends a new frame request after a
corresponding timeline/fence is destroyed.

This change therefore add a logic to check the validity of the timeline
associated with the requestor and, if it is not valid, returns an
invalid fence to notify that a frame request is not queued.

Fix: 169282240
Test: Run evs_halcamera_fuzzer and evs_virtualcamera_fuzzer
