Camera: Resize the output slot vector when needed

The output slot vector will be initialized with the total number of
buffers per output and any buffers that get attached are indexed via
the returned slot value. However there is no guarantee that the slot
will be within the [0, totalNumberOfBuffers) range. The bufffer queue
can return anything from [0, BufferQueue::NUM_BUFFER_SLOTS) and this
can result in invalid memory operations and potential instabilities.
The resolve this validate the slot value and resize the output slot
vector accordingly.
