Camera: Avoid removing valid repeating requests

Due to lock contention between the legacy camera
device implementation and the Camera2 framework,
result and error callbacks can be delayed which
can allow clients to update the repeating request
resulting in incorrect behavior.
To avoid this, check whether repeating request
errors still refer to valid and active request ids
tracked by the request queue before posting
callbacks.
